Which shell do you use?

I am just curious what y’all like to use. I tried Fish for a little bit, but I went back to Bash.

I have some bash configs that make it really nice for me.

The new line is the most important part, for me.

I use Fish when I get antsy and I wanna try something new. Otherwise I use bash.

I like for my tools to be portable, available across lots of OSes and architectures and have the vendors be nonprofits I trust. I like some more historic unix shells in principle but MAN … bash is just … so much more feature-full. You dont get bash by default on BSDs but it’s always in their ports trees too.

I occasionally use powershell entirely for work purposes but my job related powershell duties are rapidly being sunset. I also often have Nostalgia for DOS’s command.com/cmd.exe and have cranked out a batchfile or two for my employer before as well.

When I script I try to avoid bashisms though just in case I end up on a non bash environment.


I’m bash, by “default choice”. That is to say, it’s got the lion’s share of linux distros as the default, but when I tried others I didn’t like them as much.

That said, I don’t do anything with my shell. I too like portable tech in theory, but as I don’t actually do anything with it, script-wise, it is a background tech for me.

Shell prompts, on the other hand!

Why is that? It looks like a mud prompt, which I love. Newline and all.

I had a git-specific prompt on the last distro, but haven’t brought it up since, so I suppose I don’t use git as often these days, either… :thinking:

Off the top of your head, what are two or three bashisms to look out for? I am aware of this, while never knowing if I use them or not.

I like commands always being in the same place, character wise and not having to alter my visual scan of a thing because i’m 5 directories in vs 1. Like i’ll run a long command, then realize i need to make a tweak, hit up and my eyes don’t have to move really, they are focused on the spot i needed to change from before.

Bash supports some streamlined syntax for loops that don’t work in standard shell. This is where bashisms most often can creep in for me personally.

Bash provides a lot of tiny quality of life improvements and useful canned environmental variables which don’t exist in posix but are convenient. Like $RANDOM.

And while not exactly a bashism having a shebang point to bash often assumes bash’s availability and is a good way to have a script fail out of the box on BSDs. Bash comes from the ports tree not the system on BSDs, so it’s often in /usr/local/bin or /usr/pkgsrc/bin. If you want to use bash in a script and you want portability to BSD best to use: #!/usr/bin/env bash as your shebang.

Debian has a package called devscripts which has a utility called checkbashisms which will check if your using any. Not sure what its packaged as in Fedora.

bash here! i used to have more custom scripts but keep losing them. i know i should back up my dotfiles.

i also really like having a newline. i also need to have some git functionality, like saying what branch i’m on, colorizing if there are unstaged changes, and branch name completion.

once years ago someone at work downloaded a script that turned your automated test suite output into an animated nyancat in ascii art. it even played the song. it was so amazing.

I used to have git feedback, bit didn’t set it up on migration and didn’t notice. I think I really just want a single emblem to indicate I’m in a git repo.

Oh, let’s share scripts here! @tim, what’s yer config? The reason I dropped my git feedback is it dominated my bash config, something like 90 lines. Maybe there’s a better way…

I don’t have many configs to speak up, hence I haven’t reshared my config repo on atc.

When on Linux, it’s either bash or zsh, when on *BSD, either it’s bash when on not on OpenBSD, and when on OpenBSD I use ksh.
