GNOME because it works out of the box like GNOME

Weird, but good that you found out!

Are you sure the right partitions have enough space? On my tumbleweed the installer made several subvolumes i think

Alternatively you can configure a hotkey in the GNOME Settings, or the equivalent for other DEs, to execute a bash script or anything.

No issues except that if you want to source files to set env vars you might have to use a plugin (foreignenv in my case)

I still write scripts in bash. But fish’s command completion is incredible. Idk, maybe other shells can be that good as well, but fish does out of the box.

Edit: Also some people used to bash wondered what that nice shell is on a server we administrate together. They had no problems using it coming from bash.

And sticking with POSIX is good if you want to stay portable, but my shell mustn’t be portable. It should be friendly and reduce mental load.
