friend brought me some seashells
Where's tcsh?
i am using ZSH cause Fish is not POSIX compliant,which made it annoying to run scripts without rewriting them.
#!/bin/sh
Hope this helps
how about if its not in a sh file,its common for scripts to use sh or bash instead.
Linux doesnβt generally use extensions to decide what shell to use, so it doesnβt matter if itβs an sh file or not.
If it uses bash of course you can substitute #!/bin/bash
And of course you can use whatever shell you want, just saying that POSIX-compliance is not really relevant since the script can specify what shell it needs.
The file extension doesn't matter much on Linux. If you've got a shebang at the top, the shell you're running from will invoke the correct shell according to the shebang.
In some situations, you may want to use something like bash <your-script>, but that would only be when you've got a script that doesn't have a shebang, but not having one is bad practice and you really should be using them. Fish isn't the only non-POSIX shell you're going to encounter on a Linux system. Python, Perl, and probably some others will be there, and using a shebang ensures no shenanigans. So whether or not you use Fish, you should always use shebangs.
Heh. Good stuff.
More! ;D I want to see all the shells, characterised so.
... Fish [over[1]]user here. Ooh, good burn. LOL.
[1: Not just user. Overuser. I do most of my scripting in fish. Think that's not overuse yet? ... I even wrote my own text editor in fish.]
I use fish because it was the default in cachyos and decided to give it a fair shake. I like the built in syntax highlighting and fancy autocomplete but I miss bash scripting and built in commands that replace standard commands can be weird sometimes. I have not tried scripting fish, to lazy to learn yet another scripting language, especially if bash is the (almost) de-facto standard.
You can always just continue using bash scripting, with a bash shebang in your scripts, if you miss it
That's what I do. Fish is great as interactive shell, scripts don't benefit that much from it and I can use what's familiar.
The Web site for fish reads:
Finally, a command line shell for the 90s
I love them and always will.
I think I'm using fish and it works great, I love alt+s thing and auto complete thingy.
TIL the alt+s thing

I can't begin to say how superior my fish rice is to any alternative. So I won't. And I'll leave yall to flame me for implying it.
All we ask of you is that you don't reheat it in the employee break room microwave.
Unironically though. It takes time because it's structurally different than python but it's fun when you figure it out

Powershell is probably simultaneously the best and worst thing Microsoft has ever created
Second best. The best was Active Directory.
