fetch

[Features] [Dependencies] [Installation] [Post Install] [Usage] [Issues and Workarounds] [TODO] [Thanks]

This is the home of my fetch script! This script gathers info
about your system and prints it to the terminal next to an image of your choice!

Features

• Supports Linux, Mac OS X, *BSD and Windows (Cygwin)!
  • If the script isn't working on your system open an issue.
    • *BSD support is currently in testing! See issue #10
• It's Fast
  • The script makes heavy use of bash builtins and <br >string manipulation.
• Display an image next to the info. (or don't!)
  • The script can use your current wallpaper, shuffle through a directory or just <br >display an image of your choice.
    • The wallpaper function on linux uses feh, It's hard to add support <br > for other wallpaper setters as they don't provide a way of getting <br > the current wallpaper from the cli.
• Highly Customizable
  • You can customize almost everything.
    • See Usage below or lines 23-233 in script
• Take a screenshot at the end.
  • It's disabled by default and you can specify the cmd <br >to use with --scrotcmd cmd at launch or by <br >changing the value of $scrotcmd in the script.
• Smart crop (or Waifu crop)
  • See https://github.com/dylanaraps/fetch/wiki/What-is-Smart-Crop%3F

Dependencies

Required dependencies:

• Bash 4.0+
• Text formatting, dynamic image size and padding: tput
• Uptime detection: procps or procps-ng

Optional dependencies:

All OS:

• Displaying Images: w3m
  • You may also need w3m-img
• Image Cropping, Resizing etc: ImageMagick
• Current Song: mpc
• Resolution Detection: xorg-xdpyinfo
• Window manager detection: wmctrl
  • This is used as a fallback to parsing .xinitrc and $XDG_CURRENT_DESKTOP.
• Take a screenshot on script finish: scrot
  • You can change this to another program with a --scrotcmd and an in script option.

Linux | *BSD:

• Display Wallpaper: feh

Installation

Arch

1. Install fetch-git from the aur.

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. Move the script to somewhere in your $PATH or just run it from where it is.

Post Install

NOTE: For the images to be sized correctly you need to set the $font_width variable. 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.

You can customize what info to print by editing the info array near the top of the script. The array looks like this:

info=(
    "gettitle"
    "underline"
    "OS: getdistro"
    "Kernel: getkernel"
    "Uptime: getuptime"
    "Packages: getpackages"
    etc...
)

See these comments inside the script for more info: https://github.com/dylanaraps/fetch/blob/master/fetch#L29

If you don't want to edit the script you can customize everything using flags at launch!

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 \
--exclude 'Icons: getgtkicons' \

--colors 4 1 8 8 8 7 \

Issues and Workarounds

The image is rendering with black lines in Urxvt while using an xft font.

This is an issue with w3mimgdisplay and not the script. You can find a workaround here:

https://github.com/hut/ranger/issues/86#issuecomment-17346249

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

# Launch flags
--uptime_shorthand on
--gtk_shorthand on

• Edit the info array to make the subtitles shorter

• Resizing the terminal so that the lines don't wrap.

[Linux] The script hangs and doesn't display anything

This is caused by the getwallpaper function failing to find your current wallpaper and <br > imagemagick trying to crop a nonexistent image. You can fix this by installing feh and using it<br > to set your wallpaper or by changing the image source.

You can change the source by editing the $image variable or by launching the script with --image.

The possible values are:

• wall - Use the current wallpaper. (Default)
• shuffle - Shuffle through images in a directory. See $shuffledir
• path/to/img.png - Select an image to display.
• off - Disable images

TODO

Here's what's on my todo list

• Add Windows resolution detection

• Add BSD cpu speed

• Look into iterm2 image rendering

• Cleanup of info array handling

• Imagemagick optimizations

• More info outputs. Now that it's easy to customize what's printed and<br > everything is a function we can add optional support for pretty much anything.

  • Resolution (Done!)
  • GTK themes (Done!)
  • Terminal Font
  • GPU
  • IP
  • etc
