title: About zshrc
|
||||
description: It is first paper in my blog (I think I need something here for tests =)). There are many similar articles, and I'll not be an exception. I just want to show my <code>.zshrc</code> and explain what it does and why it is needed. Also any comments or additions are welcome. It is a translated paper from Russian (<a href="http://archlinux.org.ru/forum/topic/12752/">original</a>).

<h3><a name="prepare" class="anchor" href="#prepare"><span class="octicon octicon-link"></span></a>Prepare</h2>
|
||||
<p align="justify">First install recommended minima:</p>
|
||||
<pre>pacman -Sy pkgfile zsh zsh-completions zsh-syntax-highlighting</pre>
|
||||
<p align="justify"><a href="https://www.archlinux.org/packages/pkgfile/">pkgfile</a> is a very useful utility. Alo this command will install shell, additional completion and syntax highlighting.</p>
|
||||
|
||||
<h3><a name="configuration" class="anchor" href="#configuration"><span class="octicon octicon-link"></span></a>Shell configuration</h2>
|

<p align="justify">All options are avaible <a href="http://zsh.sourceforge.net/Doc/Release/Options.html">here</a>.</p>
|
||||
|

<p align="justify">Set history file and number of commands in cache of the current session and in the history file:</p>

<pre># history

HISTSIZE=500000
|

SAVEHIST=500000</pre>
|

<p align="justify">I can not remember all <code>Ctrl+</code> combinations so I bind keys to its default usages:</p>

<pre># bindkeys

|
||||
bindkey '^[[B' down-line-or-search # down arrow for fwd-history-search

bindkey '\e[1~' beginning-of-line # home
|
||||
bindkey '\e[2~' overwrite-mode # insert
|
||||
bindkey '\e[3~' delete-char # del
|
||||
bindkey '\e[4~' end-of-line # end
|
||||
bindkey '\e[5~' up-line-or-history # page-up
|
||||
bindkey '\e[6~' down-line-or-history # page-down</pre>
|
||||
<p align="justify">But in this case <code>Up</code>/<code>Down</code> arrows are used to navigate through the history based on <b>already entered part</b> of a command. And <code>PgUp</code>/<code>PgDown</code> <b>will ignore</b> already entered part of a command.</p>
|

|

|

<p align="justify">Full command autocomplete will be enabled. <code>insert-tab false</code> will enable autocomplete for <b>non-entered</b> commands. <code>max-errors</code> sets maximum number of errors that could be corrected.</p>

title: About zshrc
|
||||
description: It is first paper in my blog (I think I need something here for tests =)). There are many similar articles, and I'll not be an exception. I just want to show my <code>.zshrc</code> and explain what it does and why it is needed. Also any comments or additions are welcome. It is a translated paper from Russian (<a href="http://archlinux.org.ru/forum/topic/12752/">original</a>).

<h3><a name="prepare" class="anchor" href="#prepare"><span class="octicon octicon-link"></span></a>Prepare</h2>
|
||||
<p align="justify">First install recommended minima:</p>
|
||||
<pre>pacman -Sy pkgfile zsh zsh-completions zsh-syntax-highlighting</pre>
|
||||
<p align="justify"><a href="https://www.archlinux.org/packages/pkgfile/">pkgfile</a> is a very useful utility. Alo this command will install shell, additional completion and syntax highlighting.</p>
|
||||
|
||||
<h3><a name="configuration" class="anchor" href="#configuration"><span class="octicon octicon-link"></span></a>Shell configuration</h2>
|
||||
<p align="justify">All options are avaible <a href="http://zsh.sourceforge.net/Doc/Release/Options.html">here</a>.</p>
|
||||
|
||||
<p align="justify">Set history file and number of commands in cache of the current session and in the history file:</p>
|
||||
<pre># history
|
||||
HISTFILE=~/.zsh_history
|
||||
HISTSIZE=500000
|
||||
SAVEHIST=500000</pre>
|
||||
|
||||
<p align="justify">I can not remember all <code>Ctrl+</code> combinations so I bind keys to its default usages:</p>
|
||||
<pre># bindkeys
|

bindkey '^[[A' up-line-or-search # up arrow for back-history-search
|
||||
bindkey '^[[B' down-line-or-search # down arrow for fwd-history-search
|
||||
bindkey '\e[1~' beginning-of-line # home
|
||||
bindkey '\e[2~' overwrite-mode # insert
|
||||
bindkey '\e[3~' delete-char # del
|
||||
bindkey '\e[4~' end-of-line # end
|
||||
bindkey '\e[5~' up-line-or-history # page-up
|
||||
bindkey '\e[6~' down-line-or-history # page-down</pre>
|
||||
<p align="justify">But in this case <code>Up</code>/<code>Down</code> arrows are used to navigate through the history based on <b>already entered part</b> of a command. And <code>PgUp</code>/<code>PgDown</code> <b>will ignore</b> already entered part of a command.</p>
|
||||
|

<p align="justify">Command autocomplete:</p>
|

<pre># autocomplete
|

autoload -U compinit
|

compinit
|

zstyle ':completion:*' insert-tab false
|
||||
zstyle ':completion:*' max-errors 2</pre>
|
||||
<p align="justify">Full command autocomplete will be enabled. <code>insert-tab false</code> will enable autocomplete for <b>non-entered</b> commands. <code>max-errors</code> sets maximum number of errors that could be corrected.</p>
|
||||
|

<p align="justify">Prompt:</p>
|

<pre># promptinit

<pre># disable beeps
|

<p align="justify">Enable calculator:</p>

<pre># calc
|

title: About zshrc
|

description: It is first paper in my blog (I think I need something here for tests =)). There are many similar articles, and I'll not be an exception. I just want to show my <code>.zshrc</code> and explain what it does and why it is needed. Also any comments or additions are welcome. It is a translated paper from Russian (<a href="http://archlinux.org.ru/forum/topic/12752/">original</a>).

<h3><a name="prepare" class="anchor" href="#prepare"><span class="octicon octicon-link"></span></a>Prepare</h2>
|
||||
<p align="justify">First install recommended minima:</p>
|
||||
<pre>pacman -Sy pkgfile zsh zsh-completions zsh-syntax-highlighting</pre>
|
||||
<p align="justify"><a href="https://www.archlinux.org/packages/pkgfile/">pkgfile</a> is a very useful utility. Alo this command will install shell, additional completion and syntax highlighting.</p>
|
||||
|
||||
<h3><a name="configuration" class="anchor" href="#configuration"><span class="octicon octicon-link"></span></a>Shell configuration</h2>
|

<p align="justify">All options are avaible <a href="http://zsh.sourceforge.net/Doc/Release/Options.html">here</a>.</p>
|

|

<p align="justify">Set history file and number of commands in cache of the current session and in the history file:</p>

<pre># history

|

SAVEHIST=500000</pre>
|
||||
|

<p align="justify">I can not remember all <code>Ctrl+</code> combinations so I bind keys to its default usages:</p>

<pre># bindkeys

bindkey '^[[A' up-line-or-search # up arrow for back-history-search
|
||||
bindkey '^[[B' down-line-or-search # down arrow for fwd-history-search
|
||||
bindkey '\e[1~' beginning-of-line # home
|
||||
bindkey '\e[2~' overwrite-mode # insert
|
||||
bindkey '\e[3~' delete-char # del
|
||||
bindkey '\e[4~' end-of-line # end
|
||||
bindkey '\e[5~' up-line-or-history # page-up
|
||||
bindkey '\e[6~' down-line-or-history # page-down</pre>
|
||||
<p align="justify">But in this case <code>Up</code>/<code>Down</code> arrows are used to navigate through the history based on <b>already entered part</b> of a command. And <code>PgUp</code>/<code>PgDown</code> <b>will ignore</b> already entered part of a command.</p>
|
||||
|

<p align="justify">Command autocomplete:</p>

<pre># autocomplete

autoload -U compinit
|

|

zstyle ':completion:*' insert-tab false
|

zstyle ':completion:*' max-errors 2</pre>
|
||||
<p align="justify">Full command autocomplete will be enabled. <code>insert-tab false</code> will enable autocomplete for <b>non-entered</b> commands. <code>max-errors</code> sets maximum number of errors that could be corrected.</p>

title: About zshrc
|

description: It is first paper in my blog (I think I need something here for tests =)). There are many similar articles, and I'll not be an exception. I just want to show my <code>.zshrc</code> and explain what it does and why it is needed. Also any comments or additions are welcome. It is a translated paper from Russian (<a href="http://archlinux.org.ru/forum/topic/12752/">original</a>).

<h3><a name="prepare" class="anchor" href="#prepare"><span class="octicon octicon-link"></span></a>Prepare</h2>
|

<p align="justify">First install recommended minima:</p>

<pre>pacman -Sy pkgfile zsh zsh-completions zsh-syntax-highlighting</pre>
|
||||
<p align="justify"><a href="https://www.archlinux.org/packages/pkgfile/">pkgfile</a> is a very useful utility. Alo this command will install shell, additional completion and syntax highlighting.</p>
|

<p align="justify">I can not remember all <code>Ctrl+</code> combinations so I bind keys to its default usages:</p>

|

bindkey '\e[6~' down-line-or-history # page-down</pre>
|

<p align="justify">But in this case <code>Up</code>/<code>Down</code> arrows are used to navigate through the history based on <b>already entered part</b> of a command. And <code>PgUp</code>/<code>PgDown</code> <b>will ignore</b> already entered part of a command.</p>

title: About zshrc
|

description: It is first paper in my blog (I think I need something here for tests =)). There are many similar articles, and I'll not be an exception. I just want to show my <code>.zshrc</code> and explain what it does and why it is needed. Also any comments or additions are welcome. It is a translated paper from Russian (<a href="http://archlinux.org.ru/forum/topic/12752/">original</a>).

<p align="justify">First install recommended minima:</p>

<pre>pacman -Sy pkgfile zsh zsh-completions zsh-syntax-highlighting</pre>
|

<p align="justify"><a href="https://www.archlinux.org/packages/pkgfile/">pkgfile</a> is a very useful utility. Alo this command will install shell, additional completion and syntax highlighting.</p>

<p align="justify">But in this case <code>Up</code>/<code>Down</code> arrows are used to navigate through the history based on <b>already entered part</b> of a command. And <code>PgUp</code>/<code>PgDown</code> <b>will ignore</b> already entered part of a command.</p>

title: About zshrc
|

description: It is first paper in my blog (I think I need something here for tests =)). There are many similar articles, and I'll not be an exception. I just want to show my <code>.zshrc</code> and explain what it does and why it is needed. Also any comments or additions are welcome. It is a translated paper from Russian (<a href="http://archlinux.org.ru/forum/topic/12752/">original</a>).

<p align="justify">First install recommended minima:</p>

<p align="justify"><a href="https://www.archlinux.org/packages/pkgfile/">pkgfile</a> is a very useful utility. Alo this command will install shell, additional completion and syntax highlighting.</p>

description: It is first paper in my blog (I think I need something here for tests =)). There are many similar articles, and I'll not be an exception. I just want to show my <code>.zshrc</code> and explain what it does and why it is needed. Also any comments or additions are welcome. It is a translated paper from Russian (<a href="http://archlinux.org.ru/forum/topic/12752/">original</a>).

title: About zshrc

description: It is first paper in my blog (I think I need something here for tests =)). There are many similar articles, and I'll not be an exception. I just want to show my <code>.zshrc</code> and explain what it does and why it is needed. Also any comments or additions are welcome. It is a translated paper from Russian (<a href="http://archlinux.org.ru/forum/topic/12752/">original</a>).

title: About zshrc

description: It is first paper in my blog (I think I need something here for tests =)). There are many similar articles, and I'll not be an exception. I just want to show my <code>.zshrc</code> and explain what it does and why it is needed. Also any comments or additions are welcome. It is a translated paper from Russian (<a href="http://archlinux.org.ru/forum/topic/12752/">original</a>).

description: It is first paper in my blog (I think I need something here for tests =)). There are many similar articles, and I'll not be an exception. I just want to show my <code>.zshrc</code> and explain what it does and why it is needed. Also any comments or additions are welcome. It is a translated paper from Russian (<a href="http://archlinux.org.ru/forum/topic/12752/">original</a>).

title: About zshrc
|
||||
description: It is first paper in my blog (I think I need something here for tests =)). There are many similar articles, and I'll not be an exception. I just want to show my <code>.zshrc</code> and explain what it does and why it is needed. Also any comments or additions are welcome. It is a translated paper from Russian (<a href="http://archlinux.org.ru/forum/topic/12752/">original</a>).

<h3><a name="prepare" class="anchor" href="#prepare"><span class="octicon octicon-link"></span></a>Prepare</h2>
|
||||
<p align="justify">First install recommended minima:</p>
|
||||
<pre>pacman -Sy pkgfile zsh zsh-completions zsh-syntax-highlighting</pre>
|
||||
<p align="justify"><a href="https://www.archlinux.org/packages/pkgfile/">pkgfile</a> is a very useful utility. Alo this command will install shell, additional completion and syntax highlighting.</p>
|
||||
|
||||
<h3><a name="configuration" class="anchor" href="#configuration"><span class="octicon octicon-link"></span></a>Shell configuration</h2>
|
||||
<p align="justify">All options are avaible <a href="http://zsh.sourceforge.net/Doc/Release/Options.html">here</a>.</p>
|
||||
|
||||
<p align="justify">Set history file and number of commands in cache of the current session and in the history file:</p>
|
||||
<pre># history
|
||||
HISTFILE=~/.zsh_history
|
||||
HISTSIZE=500000
|
||||
SAVEHIST=500000</pre>
|
||||
|
||||
<p align="justify">I can not remember all <code>Ctrl+</code> combinations so I bind keys to its default usages:</p>
|
||||
<pre># bindkeys
|
||||
bindkey '^[[A' up-line-or-search # up arrow for back-history-search
|
||||
bindkey '^[[B' down-line-or-search # down arrow for fwd-history-search
|
||||
bindkey '\e[1~' beginning-of-line # home
|
||||
bindkey '\e[2~' overwrite-mode # insert
|
||||
bindkey '\e[3~' delete-char # del
|
||||
bindkey '\e[4~' end-of-line # end
|
||||
bindkey '\e[5~' up-line-or-history # page-up
|
||||
bindkey '\e[6~' down-line-or-history # page-down</pre>
|
||||
<p align="justify">But in this case <code>Up</code>/<code>Down</code> arrows are used to navigate through the history based on <b>already entered part</b> of a command. And <code>PgUp</code>/<code>PgDown</code> <b>will ignore</b> already entered part of a command.</p>
|
||||
|

<p align="justify">Command autocomplete:</p>
|

<pre># autocomplete

autoload -U compinit
|

compinit
|

zstyle ':completion:*' insert-tab false
|
||||
zstyle ':completion:*' max-errors 2</pre>
|
||||
<p align="justify">Full command autocomplete will be enabled. <code>insert-tab false</code> will enable autocomplete for <b>non-entered</b> commands. <code>max-errors</code> sets maximum number of errors that could be corrected.</p>
|
||||
|

<p align="justify">Prompt:</p>
|

<pre># promptinit

<p align="justify">Enable calculator:</p>

<pre># calc

title: About zshrc
|
||||
description: It is first paper in my blog (I think I need something here for tests =)). There are many similar articles, and I'll not be an exception. I just want to show my <code>.zshrc</code> and explain what it does and why it is needed. Also any comments or additions are welcome. It is a translated paper from Russian (<a href="http://archlinux.org.ru/forum/topic/12752/">original</a>).

<h3><a name="prepare" class="anchor" href="#prepare"><span class="octicon octicon-link"></span></a>Prepare</h2>
|
||||
<p align="justify">First install recommended minima:</p>
|
||||
<pre>pacman -Sy pkgfile zsh zsh-completions zsh-syntax-highlighting</pre>
|
||||
<p align="justify"><a href="https://www.archlinux.org/packages/pkgfile/">pkgfile</a> is a very useful utility. Alo this command will install shell, additional completion and syntax highlighting.</p>
|
||||
|
||||
<h3><a name="configuration" class="anchor" href="#configuration"><span class="octicon octicon-link"></span></a>Shell configuration</h2>
|
||||
<p align="justify">All options are avaible <a href="http://zsh.sourceforge.net/Doc/Release/Options.html">here</a>.</p>
|
||||
|
||||
<p align="justify">Set history file and number of commands in cache of the current session and in the history file:</p>
|
||||
<pre># history
|
||||
HISTFILE=~/.zsh_history
|
||||
HISTSIZE=500000
|
||||
SAVEHIST=500000</pre>
|
||||
|
||||
<p align="justify">I can not remember all <code>Ctrl+</code> combinations so I bind keys to its default usages:</p>
|

<pre># bindkeys
|

bindkey '^[[A' up-line-or-search # up arrow for back-history-search
|
||||
bindkey '^[[B' down-line-or-search # down arrow for fwd-history-search
|
||||
bindkey '\e[1~' beginning-of-line # home
|
||||
bindkey '\e[2~' overwrite-mode # insert
|
||||
bindkey '\e[3~' delete-char # del
|
||||
bindkey '\e[4~' end-of-line # end
|
||||
bindkey '\e[5~' up-line-or-history # page-up
|
||||
bindkey '\e[6~' down-line-or-history # page-down</pre>
|
||||
<p align="justify">But in this case <code>Up</code>/<code>Down</code> arrows are used to navigate through the history based on <b>already entered part</b> of a command. And <code>PgUp</code>/<code>PgDown</code> <b>will ignore</b> already entered part of a command.</p>
|
||||
|

<p align="justify">Command autocomplete:</p>
|

<pre># autocomplete
|

autoload -U compinit
|

compinit
|

zstyle ':completion:*' insert-tab false
|
||||
zstyle ':completion:*' max-errors 2</pre>
|
||||
<p align="justify">Full command autocomplete will be enabled. <code>insert-tab false</code> will enable autocomplete for <b>non-entered</b> commands. <code>max-errors</code> sets maximum number of errors that could be corrected.</p>
|

<pre># calc

title: About zshrc
|
||||
description: It is first paper in my blog (I think I need something here for tests =)). There are many similar articles, and I'll not be an exception. I just want to show my <code>.zshrc</code> and explain what it does and why it is needed. Also any comments or additions are welcome. It is a translated paper from Russian (<a href="http://archlinux.org.ru/forum/topic/12752/">original</a>).

<h3><a name="prepare" class="anchor" href="#prepare"><span class="octicon octicon-link"></span></a>Prepare</h2>
|
||||
<p align="justify">First install recommended minima:</p>
|
||||
<pre>pacman -Sy pkgfile zsh zsh-completions zsh-syntax-highlighting</pre>
|
||||
<p align="justify"><a href="https://www.archlinux.org/packages/pkgfile/">pkgfile</a> is a very useful utility. Alo this command will install shell, additional completion and syntax highlighting.</p>
|
||||
|
||||
<h3><a name="configuration" class="anchor" href="#configuration"><span class="octicon octicon-link"></span></a>Shell configuration</h2>
|
||||
<p align="justify">All options are avaible <a href="http://zsh.sourceforge.net/Doc/Release/Options.html">here</a>.</p>
|
||||
|
||||
<p align="justify">Set history file and number of commands in cache of the current session and in the history file:</p>
|
||||
<pre># history
|
||||
HISTFILE=~/.zsh_history
|
||||
HISTSIZE=500000
|
||||
SAVEHIST=500000</pre>
|
||||
|
||||
<p align="justify">I can not remember all <code>Ctrl+</code> combinations so I bind keys to its default usages:</p>
|
||||
<pre># bindkeys
|
||||
bindkey '^[[A' up-line-or-search # up arrow for back-history-search
|
||||
bindkey '^[[B' down-line-or-search # down arrow for fwd-history-search
|
||||
bindkey '\e[1~' beginning-of-line # home
|
||||
bindkey '\e[2~' overwrite-mode # insert
|
||||
bindkey '\e[3~' delete-char # del
|
||||
bindkey '\e[4~' end-of-line # end
|
||||
bindkey '\e[5~' up-line-or-history # page-up
|
||||
bindkey '\e[6~' down-line-or-history # page-down</pre>
|
||||
<p align="justify">But in this case <code>Up</code>/<code>Down</code> arrows are used to navigate through the history based on <b>already entered part</b> of a command. And <code>PgUp</code>/<code>PgDown</code> <b>will ignore</b> already entered part of a command.</p>
|
||||
|
||||
<p align="justify">Command autocomplete:</p>
|

<pre># autocomplete
|

autoload -U compinit
|

compinit
|

zstyle ':completion:*' insert-tab false
|
||||
zstyle ':completion:*' max-errors 2</pre>
|
||||
<p align="justify">Full command autocomplete will be enabled. <code>insert-tab false</code> will enable autocomplete for <b>non-entered</b> commands. <code>max-errors</code> sets maximum number of errors that could be corrected.</p>
|
||||
|

<p align="justify">Prompt:</p>
|

<pre># promptinit

<pre># disable beeps
|

|

<p align="justify">Enable calculator:</p>
|

<pre># calc
|

<p align="justify">Append history (<b>do not recreate</b> the history file):</p>

title: About zshrc
|
||||
description: It is first paper in my blog (I think I need something here for tests =)). There are many similar articles, and I'll not be an exception. I just want to show my <code>.zshrc</code> and explain what it does and why it is needed. Also any comments or additions are welcome. It is a translated paper from Russian (<a href="http://archlinux.org.ru/forum/topic/12752/">original</a>).

<h3><a name="prepare" class="anchor" href="#prepare"><span class="octicon octicon-link"></span></a>Prepare</h2>
|
||||
<p align="justify">First install recommended minima:</p>
|
||||
<pre>pacman -Sy pkgfile zsh zsh-completions zsh-syntax-highlighting</pre>
|
||||
<p align="justify"><a href="https://www.archlinux.org/packages/pkgfile/">pkgfile</a> is a very useful utility. Alo this command will install shell, additional completion and syntax highlighting.</p>
|
||||
|
||||
<h3><a name="configuration" class="anchor" href="#configuration"><span class="octicon octicon-link"></span></a>Shell configuration</h2>
|

<p align="justify">All options are avaible <a href="http://zsh.sourceforge.net/Doc/Release/Options.html">here</a>.</p>
|

|

<p align="justify">Set history file and number of commands in cache of the current session and in the history file:</p>

<pre># history

|

SAVEHIST=500000</pre>
|
||||
|

<p align="justify">I can not remember all <code>Ctrl+</code> combinations so I bind keys to its default usages:</p>

<pre># bindkeys
|

bindkey '^[[A' up-line-or-search # up arrow for back-history-search
|
||||
bindkey '^[[B' down-line-or-search # down arrow for fwd-history-search
|
||||
bindkey '\e[1~' beginning-of-line # home
|
||||
bindkey '\e[2~' overwrite-mode # insert
|
||||
bindkey '\e[3~' delete-char # del
|
||||
bindkey '\e[4~' end-of-line # end
|
||||
bindkey '\e[5~' up-line-or-history # page-up
|
||||
bindkey '\e[6~' down-line-or-history # page-down</pre>
|
||||
<p align="justify">But in this case <code>Up</code>/<code>Down</code> arrows are used to navigate through the history based on <b>already entered part</b> of a command. And <code>PgUp</code>/<code>PgDown</code> <b>will ignore</b> already entered part of a command.</p>
|
||||
|

<p align="justify">Command autocomplete:</p>

<pre># autocomplete

autoload -U compinit
|

zstyle ':completion:*' insert-tab false
|

zstyle ':completion:*' max-errors 2</pre>
|
||||
<p align="justify">Full command autocomplete will be enabled. <code>insert-tab false</code> will enable autocomplete for <b>non-entered</b> commands. <code>max-errors</code> sets maximum number of errors that could be corrected.</p>

title: About zshrc
|

description: It is first paper in my blog (I think I need something here for tests =)). There are many similar articles, and I'll not be an exception. I just want to show my <code>.zshrc</code> and explain what it does and why it is needed. Also any comments or additions are welcome. It is a translated paper from Russian (<a href="http://archlinux.org.ru/forum/topic/12752/">original</a>).

|

<p align="justify">First install recommended minima:</p>

<pre>pacman -Sy pkgfile zsh zsh-completions zsh-syntax-highlighting</pre>
|
||||
<p align="justify"><a href="https://www.archlinux.org/packages/pkgfile/">pkgfile</a> is a very useful utility. Alo this command will install shell, additional completion and syntax highlighting.</p>

bindkey '\e[6~' down-line-or-history # page-down</pre>
|

<p align="justify">But in this case <code>Up</code>/<code>Down</code> arrows are used to navigate through the history based on <b>already entered part</b> of a command. And <code>PgUp</code>/<code>PgDown</code> <b>will ignore</b> already entered part of a command.</p>

title: About zshrc
|

description: It is first paper in my blog (I think I need something here for tests =)). There are many similar articles, and I'll not be an exception. I just want to show my <code>.zshrc</code> and explain what it does and why it is needed. Also any comments or additions are welcome. It is a translated paper from Russian (<a href="http://archlinux.org.ru/forum/topic/12752/">original</a>).

<p align="justify">First install recommended minima:</p>

<p align="justify">But in this case <code>Up</code>/<code>Down</code> arrows are used to navigate through the history based on <b>already entered part</b> of a command. And <code>PgUp</code>/<code>PgDown</code> <b>will ignore</b> already entered part of a command.</p>

title: About zshrc
|

description: It is first paper in my blog (I think I need something here for tests =)). There are many similar articles, and I'll not be an exception. I just want to show my <code>.zshrc</code> and explain what it does and why it is needed. Also any comments or additions are welcome. It is a translated paper from Russian (<a href="http://archlinux.org.ru/forum/topic/12752/">original</a>).

<p align="justify">First install recommended minima:</p>

title: About zshrc
|

description: It is first paper in my blog (I think I need something here for tests =)). There are many similar articles, and I'll not be an exception. I just want to show my <code>.zshrc</code> and explain what it does and why it is needed. Also any comments or additions are welcome. It is a translated paper from Russian (<a href="http://archlinux.org.ru/forum/topic/12752/">original</a>).

title: About zshrc

description: It is first paper in my blog (I think I need something here for tests =)). There are many similar articles, and I'll not be an exception. I just want to show my <code>.zshrc</code> and explain what it does and why it is needed. Also any comments or additions are welcome. It is a translated paper from Russian (<a href="http://archlinux.org.ru/forum/topic/12752/">original</a>).

title: About zshrc

description: It is first paper in my blog (I think I need something here for tests =)). There are many similar articles, and I'll not be an exception. I just want to show my <code>.zshrc</code> and explain what it does and why it is needed. Also any comments or additions are welcome. It is a translated paper from Russian (<a href="http://archlinux.org.ru/forum/topic/12752/">original</a>).

description: It is first paper in my blog (I think I need something here for tests =)). There are many similar articles, and I'll not be an exception. I just want to show my <code>.zshrc</code> and explain what it does and why it is needed. Also any comments or additions are welcome. It is a translated paper from Russian (<a href="http://archlinux.org.ru/forum/topic/12752/">original</a>).
