1. I use Bash.
2. I write #!/bin/sh
3. I don’t have 2 folders.
4. I share my shell scripts.
5. I sync my folders using rsync.
6. Creating your shortcuts is fine, since original commands are still available.

Yes fish is great. It has some special syntax for functions, I will add my configs soo.

set fish_greeting is useful to silence it.

User scripts can go to ~/.local/bin which is already in the path.

You can split up your shell configs into topics, and put them into ~/.config/fish/conf.d/abc.conf

A good idea i have been spreading around relevant people lately is to use ShellCheck as you code in Bash, integrate it in your workflow, editor or IDE as relevant to you (there’s a commandline tool as well as being available for editors in various forms), and pass your scripts through it, trying to get the warnings to go away. That should fix many obvious errors and clean up your code a bit.

#!/usr/bin/env bash

A folder dotfiles as git repository and a dotfiles/install that soft links all configurations into their places.

Two files, ~/.zshrc (without secrets, could be shared) and another for secrets (sourced by .zshrc if exist secrets).

Use

set -x

For debugging

• I use bash, because I never had the time to learn anything else.
• Like @[email protected] said, I use the #!/usr/bin/env bash shebang.
• Nope
• Also nope
• Nope. Shell scripts reside in Git repos on Gitlab/Gitea/Forgejo and are checked out using Ansible playbooks onto the servers as necessary.
• For scripts? Python. Read this blog post by the great @[email protected]. For interactive use? bash is just fine for me, though I’ve customized it using Starship and created some aliases to have colored/pretty output where possible.
• Use shellcheck before running your scripts in production, err on the side of caution, set -o pipefail. There are best practices guides for Bash, use those and you’ll probably be fine.
• Be prepared to shave yaks. Take breaks, touch grass, pet a dog. Use set -x inside your Bash script or bash -x scriptname on the CLI for debugging. Remember that you can always fallback to interactive CLI to test/prepare commands before you put them into your script. Think before you type. Test. Optimize only what needs optimization. Use long options for readability. And remember: Always code as if the guy who ends up maintaining your code will be a violent psychopath who knows your address.
• Nope, it’s absolutely not bad practice to create aliases to save you some typing in interactive shell. You shouldn’t use them inside your scripts though, because they might/will not be available in other environments.

I switched to fish because it has tab completion Yeah, so does Bash, just install it.

Oh, I also “curate” a list of Linux tools that I like, that are more modern alternatives to “traditional” Linux tools or that provide information I would otherwise not easily get. I’ll post i

I use bash and I usually put /bin/bash in my scrtipts, because that’s where I know it works. /bin/sh is only if it works on many/all shells.

I don’t have many such scripts, so I just have one. I don’t really share them, as they are made for my usecase. If I do create something that I think will help others, then yes, I share them in git somewhere.

I do have a scripts folder in my Nextcloud that I sync around with useful scripts.

Some of your examples can probably just be made into aliases with alias alias_name="command_to_run".

Am I missing something - doesn’t bash have tab completion or of the box?

That’s the way I do it:

#!/usr/bin/env nix
#! nix shell nixpkgs#nushell <optionally more dependencies>  --command nu

<script content>

But those scripts are only used by me

Do you use bash? Yes because it is everywhere and available by default.

I use Bash for scripts, though my interactive shell is Fish.

Usually I use #!/usr/bin/env bash as shebang. This has the advantage of searching your PATH for Bash instead of hardcoding it.

My folders are only differentiated by those in my PATH and those not.

Most of my scripts can be found here. They are purely desktop use, no syncing to any servers. Most would be useless there.

For good practice, I’d recommend using set -euo pipefail to make Bash slightly less insane and use shellcheck to check for issues.
This is personal preference, but you could avoid Bashisms like [[ and stick to POSIX sh. (Use #!/usr/bin/env sh then.)

With shortened commands the risk is that you might forget how the full command works. How reliant you want to be on those commands being present is up to you. I wouldn’t implement them as scripts though, just simple aliases instead.
Scripts only make sense if you want to do something slightly more complex over multiple lines for readability.

I use bash as my interactive shell. When ~20 years ago or so I encountered “smart” tab completion for the first time, I immediately disabled that and went back to dumb completion, because it caused multi-second freezes when it needed to load stuff from disk. I also saw it refuse to complete filenames because they had the wrong suffix. Maybe I should try to enable that again, see if it works any better now. It probably does go faster now with the SSDs.

I tried OpenBSD at some point, and it came with some version of ksh. Seems about equivalent to bash, but I had to modify some of my .bashrc so it would work on ksh. I would just stick to the default shell, whatever it is, it’s fine.

I try to stick to POSIX shell for scripts. I find that I don’t need bashisms very often, and I’ve used systems without bash on them. Most bash-only syntax has an equivalent that will work on POSIX sh. I do use bash if I really need some bash feature (I recently wanted to set -o pipefail, which dash cannot do apparently, and the workaround is really annoying).

Do not use #!/bin/sh if you’re not writing bash-only scripts. This will break on Debian, Ubuntu, BSD, busybox etc. because /bin/sh is not bash on those systems.

• Do you use bash? If not, which one do you use? zsh, fish? Why do you do it?
• Do you write #!/bin/bash or #!/bin/sh? Do you write fish exclusive scripts?

I use bash, and I use #!/bin/bash for my scripts. Some are POSIX compliant, some have bashisms. But I really don’t care about bashisms, since I explicitly set the bash as interpreter. So no, no fish exclusive scripts, but some “bash exclusive” scripts. Since fish is aimed towards being used as interactive shell I don’t see a real reason to use it as interpreter for scripts anyways.

• Do you have two folders, one for proven commands and one for experimental?
• Do you publish/ share those commands?
• Do you sync the folder between your server and your workstation?

I have my scripts in $HOME/.scripts and softlink them from a directory in $PATH. Some of the scripts are versioned using Git, but the repository is private and I do not plan sharing them because the repoand the scripts scripts contain some not-tho-share information and mostly are simply not useful outside my carefully crafted and specific environment. If I want to share a script, I do it individually or make a proper public Git repository for it.

Since my server(s) and my workstations have different use cases I do not share any configuration between them. I share some configuration between different workstations, though. My dotfiles repository is mainly there for me to keep track of changes in my dotfiles.

is it bad practice to create a handful of commands

It becomes bad practice if it is against your personal or corporate guidelines regarding best practices. While it is not particularly bad or insecure, etc. to create bash scripts containing a single command, maybe use an alias instead. The $1 is automatically the first parameter after typing the alias in the shell.

alias podup="podman compose up -d"
alias poddown="podman compose down"
alias podlog="podman logs -f --tail 20"

Not quite sure about the podman syntax, if podman exec /bin/sh -it "$1" also works, you can use alias podenter="podman exec /bin/sh -it, Otherwise a simple function would do the trick.

Bash script for simple things (although Fish is my regular shell) and Node or Python scripts for complex things. Using #!/usr/bin/env node works just like it would for Bash so you know.

Yes, using bash on all boxen.

Scripts start with #!/bin/sh ,because, that gives quicker execution times.

Any simple aliases, I put in .bash_aliases

Tried tcsh and zsh around 30yrs ago, all bash since then.
