fetch

[Features] [Dependencies] [Installation] [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 and Windows (Cygwin)!
  • If the script isn't working on your system open an issue.
• It's Fast
  • The script makes heavy use of bash builtins and <br >string manipulation.
• Display an image next to the info. (or not)
  • The script can use your wallpaper, shuffle through a directory or just <br >display an image.
    • 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 > 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

These are the script's required dependencies

• Bash 4.0+
  • For those of you on OS X not wanting to update bash, the script <br >also works with zsh. All you have to do is change the shebang at <br >the top to #!/bin/zsh.
• Text formatting, dynamic image size and padding: tput
• Uptime detection: procps or procps-ng

These are the script's optional dependencies:

• Displaying Images: w3m
  • You may also need w3m-img
• Image Cropping: ImageMagick
• Display Wallpaper: feh
• 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.

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.

Usage

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

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.

TODO

Here's what's on my todo list

• Add Windows resolution detection

• 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
