Features

• Supports Linux, Mac OS X, BSD (FreeBSD, OpenBSD & NetBSD) and Windows (Cygwin)
• Display a full color image, a file containing ascii art or your distro's logo in ascii next to the info.
• The script is fast. We use bash builtins wherever possible and only spawn external processes when necessary.
• Take a screenshot of your desktop on script finish.
• Customize which info is displayed, where it's displayed and when it's displayed.
  • See this wiki page

Dependencies

Required dependencies:

• Bash 4.0+
• procps-ng
  • Not required on OS X

Optional dependencies:

• Displaying images: w3m-img [1] or iTerm2 [2]
• Thumbnail creation: imagemagick

Linux / BSD

• Window Manager: wmctrl [3]
• Wallpaper: feh, nitrogen or gsettings
• Current Song: mpc or cmus
• Resolution: xorg-xdpyinfo
• Screenshot: scrot [4]

[1] w3m-img is sometimes bundled together with w3m.

[2] You can enable the iTerm2 image backend by using the launch flag --image_backend iterm2 or by<br > changing the config option $image_backend to iterm2.

[3] You should install wmctrl if the builtin window manager detection isn't working for you. The builtin<br > detection works for most people and is generally faster which is why wmctrl isn't default.

[4] You can use the launch flag --scrot_cmd or change the config option $scrot_cmd to your screenshot<br > program's cmd and fetch will use it instead of scrot.

Installation

Arch

1. Install fetch-git from the aur.

Gentoo / Funtoo

1. Add the 3rd party repo
   • layman -o https://gist.githubusercontent.com/z1lt0id/24d45b15800b98975260/raw/2fdf6645cdc3c1ca0b0af83a7bf8f86598e386ae/fs0ciety.xml -f -a fs0ciety
2. Sync the repos
   • layman -S
3. To enable w3m and scrot support, enable the appropriate flags.
   • echo "x11-apps/fetch" >> /etc/portage/package.use
4. Install the package
   • emerge -a x11-apps/fetch

Others

1. Download the latest source at https://github.com/dylanaraps/fetch
2. Run make install inside the script directory to install the script.
   • El Captain: PREFIX=/usr/local make install

NOTE: Fetch can be uninstalled easily using make uninstall.

NOTE: Fetch can also be run from any directory like a normal script,<br > you'll just be missing the ascii distro logos and automatic config file creation.

Post Install

Using the config file

Fetch will by default create a config file at $HOME/.config/fetch/config and this file<br > contains all of the script's options/settings. The config file allows you to keep your<br > customizations between script versions and allows you to easily share your customizations<br > with other people.

You can launch the script without a config file by using the flag --config none and you can<br > specify a custom config location using --config path/to/config.

Sizing the image correctly

NOTE: For the images to be sized correctly you need to set the $font_width variable.<br > If you don't know your font width in pixels keep trying values until the image is half the<br > terminal width.

Once font_width is set the image will by default take up half the terminal width. You can<br > use the launch flag --size px or change the config option $image_size to set it to a custom<br > size in pixels.

You can also use the launch flag --font_width to set it on the fly.

Setting the prompt height

If your shell prompt's height is greater than 1 line high, you'll need to change a config<br > option to avoid issues with the top lines in the script output getting cut off. Set the variable<br > $prompt_height to your shell prompt's height in lines or use the launch flag --prompt_height.

Customizing what info gets displayed

In the config file there's a function that allows you to customize all of the info that<br > gets displayed.

Here's what you can do:

• Add new info lines
• Change the ordering of the info
• Remove unwanted info lines
• Use bash syntax to control when info gets displayed

See this wiki page that goes more in-depth about it:

https://github.com/dylanaraps/fetch/wiki/Customizing-Info

Customizing the script using a custom alias

If you don't want to use the config file you can customize almost everything using launch flags!

Here's what my fetch alias looks like:

alias fetch2="fetch \
--block_range 1 8 \
--line_wrap off \
--bold off \
--uptime_shorthand on \
--gtk_shorthand on \
--colors 4 1 8 8 8 7 \

Frequently Asked Questions

How do I enable screenfetch mode?

Launching the script with --ascii distro or setting ascii="distro" and image="ascii" <br > inside the config file will launch the script in "screenfetch mode". The script will<br > display your distro's ascii next to the info, exactly like screenfetch.

NOTE: If you don't have w3m-img or imagemagick installed screenfetch mode will be<br > used automatically

Why doesn't fetch support my wallpaper setter?

It's hard to add support for other wallpaper setters as they don't provide a way of <br > getting the current wallpaper from the cli.

If your wallpaper setter does provide a way of getting the current wallpaper or you<br > know where it's stored then adding support won't be a problem!<br >

Issues and Workarounds

The text is too long for my terminal window and wraps to the next line

There are a few ways to fix this.

• Disable line wrapping with line_wrap=off in the script or with the launch flag --line_wrap off
• The uptime and gtk info lines each have a shorthand option that makes their output smaller. You can <br > enable them by changing these variables or using these flags.

# Config options
uptime_shorthand="on"
gtk_shorthand="on"
gpu_shorthand="on"
birthday_shorthand="on"

# Launch flags
--uptime_shorthand on
--gtk_shorthand on
--gpu_shorthand on
--birthday_shorthand on

• Edit the config to make the subtitles shorter
• Resizing the terminal so that the lines don't wrap.

The text is pushed over too far to the right

The easiest way to fix this is to change the value of --gap or $gap<br > to a negative value. For example --gap -10 will move the text 10 spaces to the left.

getgpu doesn't show my exact video card name

If your lspci | grep "VGA" output looks like this:

01:00.0 VGA compatible controller: NVIDIA Corporation Device 1401 (rev a1)

Instead of this:

01:00.0 VGA compatible controller: NVIDIA Corporation GM206 [GeForce GTX 960] (rev a1)

Then you're affected by the issue.

This is caused by your /usr/share/misc/pci.ids\* files being outdated and you can fix it<br > by running this command as root.

sudo update-pciids
