Features

• Supports Linux, Mac OS X, BSD and Windows (Cygwin)
• Display a full color image, a file containing ascii art or your distro's logo in ascii next to the info.

Dependencies

Required dependencies:

All OS:

• Bash 4.0+

Linux / BSD / Windows:

• Uptime detection: procps or procps-ng

Optional dependencies:

NOTE: If w3m or Imagemagick aren't found then image support will be disabled.

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. Make the file executable using chmod. chmod +x /path/to/fetch
3. Symlink fetch to somehwere in your $PATH. ln -s /path/to/fetch /path/to/$PATH
   • Fetch now comes with ascii art and a config file so moving<br > just the script file will disable these features.

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 sized correctly.

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

Customizing what info gets displayed

At the top of the script and in the config file there's a function that allows you to customize<br > all of the info that 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 edit the script 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 script will launch the script in "screenfetch mode". The script will display your<br > distro's ascii next to the info, exactly like screenfetch.

Why doesn't fetch support my wallpaper setter?

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

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

Issues and Workarounds

The image is blank and won't show up.

The text is too long for my terminal window and wraps to the next line causing the image to not render correctly.

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.

# In script options
uptime_shorthand="on"
gtk_shorthand="on"
gpu_shorthand="on"

# Launch flags
--uptime_shorthand on
--gtk_shorthand on
--gpu_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
