+title: How to upload screenshots to S3 from linux
+short: upload-screenshots-to-s3
+---
+For some reasons I'm forced to upload screenshots to S3 instead of public resourses.
+This paper describes simple solution which allows to upload screenshots and get
+link to it directly from screenshot tool.
+
+<!--more-->
+
+## Requirements
+
+1. Screenshot tool which allows to use custom applications to open image (I use
+[Spectacle](//www.kde.org/applications/graphics/spectacle/)).
+2. Installed and configured [s3cmd](//s3tools.org/s3cmd).
+3. Installed [xsel](//linux.die.net/man/1/xsel) to copy URL to clipboard.
+4. Text editor.
+
+## Desktop file
+
+Create desktop file in `$HOME/.local/share/applications/s3cmd.desktop` with the
+following content
+
+```ini
+[Desktop Entry]
+Name=s3cmd
+Exec=s3cmd put --acl-public %U "s3://bucket-name/path/to/screenshots/`uuidgen`.png" | grep "Public URL" | cut -d ':' -f 2- | xsel -bi
+Icon=image
+Type=Application
+Terminal=true
+Categories=Graphics;
+MimeType=image/png;
+```
+
+The magic is in `Exec=` parameter. It uses path to temporary created file (`%U`),
+uploads image to S3 by using `s3cmd` and gets URL from it with some bash magic.
+
+## Usage
+
+Just do screenshot and open it with `s3cmd`.
