Here you can find the repo if you want to use it. The jist of it is that you configure the source code like you would dwm, or st and then you have a very fast and light fetch program. For the ascii it takes a file called conf found in $HOME/.config/cfetch/ so you can easily change the ascii output. The repo has two ascii files one for gentoo and one for openbsd by default, check it out, critisize it do whatever.
It's great!
But is it really that different from writing a shell-script with those commands?
Not op, but functionally no, as it would be rare a user wouldn't use bash to run it but it does remove the dependance on a shell, and is likely quicker. It could, technically, be run without a shell too. It would also work on non posix compliant shells, or anything which can run the command. Not something that this application would be likely to do, it is just a fetch app, but it's still a fun little project
Thanks for clarifying!
