fet.sh

a fetch written in POSIX shell with no external commands

Installing

Arch: fet.sh-git (AUR)
Gentoo: app-misc/fetsh (GURU overlay)
KISS: fetsh (Community)
Nix: fet-sh (nixpkgs-unstable)
Alternatively, copy fet.sh to somewhere in $PATH and mark it as executable (chmod +x fet.sh)

Customization

fet.sh has a few basic configuration options using environment variables, for example:

$ info='n os wm sh n' fet.sh

Supported options are:

• accent (0-7)
• info
• separator
• colourblocks

For less trivial configuration I recommend editing the script, I tried to keep it simple.

Known Issues

MacOS, BSD, and Android don't show much info.

fet.sh's Issues

i3blocks is detected as WM

In the WM case statement, i3blocks is considered to be a valid name:

#14 fixes it on my system, but that's only because I don't randomize my PIDs. If I were to do that, i3blocks would still show up as my WM 50% of the time.

Useless use of echo.

TL;DR:

set -- $(echo ...) is useless use of echo.

---

It happens three times:

• https://github.com/6gk/fet.sh/blob/master/fet.sh#L123: set -- $(echo /var/lib/pacman/local/*)
• https://github.com/6gk/fet.sh/blob/master/fet.sh#L128: set -- $(echo /var/db/xbps/.*)
• https://github.com/6gk/fet.sh/blob/master/fet.sh#L133: set -- $(echo /var/db/pkg/*/*)

There's no need of $(echo ...); the shell will expand the globbing patterns, and needs no "help".

Also, instead of three pkgs=$#'s, use only one after performing the checks (i.e., after line 136).

Incorrect package count

https://github.com/6gk/fet.sh/blob/5d432d2c67f0723a1dde41ad066d4bc2fc15282a/fet.sh#L109

Running fet.sh on KISS Linux i get a wrong package count.

dm@mm
os ~ kiss
sh ~ sh
wm ~ sowm
up ~ 06:35
kern ~ 5.4.70
pkgs ~ 2
term ~ tmux: server
▅▅▅▅▅▅▅▅▅▅▅▅

Lack of information outputted for non-linux os's.

Made to address the readme. It's here so that it can be motivation for others (and maybe me 😳) to resolve it.

icewmbg detected instead of IceWM

Its name is IceWM, the icewmbg process only sets the background.
I'm using Debian sid.

Too aggressive terminal name filter

https://github.com/6gk/fet.sh/blob/de8e83b22cb36097ad6ec6243073417549fcd558/fet.sh#L47

*init* filters out miniterm which I use. *init would also filter xinit out which is the only reason for the filter, I think. If not just ignore this issue.

host says 'System Product Name' instead of my motherboard model

I'm not sure what kind of info you would like from me to fix this, but I'll paste a screenshot of the output

blocks look wierd

when i run fet.sh the blocks are wierdly displayed, they are not displayed in my colorscheme and they are very small, and have weird small spaces between them tried resizing the terminal ctrl + or - but it doesn't work

Resolution

Was wondering if there was a way to display resolution while staying POSIX sh only. This is the best I could come up with so far. May not work on all versions of xorg/configurations and could break in other ways. Perhaps someone could come up with something better. :)

Incorrect number of packages on Arch

Hello,

Thanks for sharing this fetch script! I have noticed one discrepancy however; it looks like the package count for Arch linux is slightly off; I don't know POSIX at all but it looks like the relevant code in fet.sh is counting all files and directories rather than just the directories of the package. On my system, my /var/lib/pacman/local/ contains a ALPM_DB_VERSION file which I don't think is a part of any singular package.

linux only

doesn’t work outside of linux
