In the context of software it seems like the word has pretty broadly adopted the meaning of "side-effect free". It's even made it to Wikipedia: https://en.wikipedia.org/wiki/Idempotence#Computer_science_m... One notable example: Stripe's "idempotency keys": https://stripe.com/blog/idempotency

I understand 'idempotent' not as 'having no side effects' but as 'having the same side effects whether performed one or many times'. This is side-effect free: echo hello This is side-effectful, but idempotent: echo hello >world This is side-effectful and not idempotent: echo hello >>world

Mathematical idempotency depends heavily on the function's domain. It's not too challenging to construct a non-idempotent function that has an idempotent restriction. So depending on what your domain of interest some operations may be idempotent or not.

In the hello world example, I guess we are considering 'echo' as the function. If then if we consider stdout and echo's args to be the same, echo will be idempotent.

However, stdout and command args are pretty different things on any system I know. If we care about things like command line history, then clearly 'echo hello world' is not idempotent.

The danger of this is if you accidentally write 'git git something' into a shell script and it works on your machine, then you commit the script to a repo and it doesn't work for anyone else. I suppose this is a problem with any alias.

One way around that issue is to prefix commands you intend to share with backslash:

    $ \gstatus
    gstatus: command not found
vs

    $ gstatus
    git status stuff
The backslash just disables alias expansion. This works on all shells I'm aware of. It won't help with other portability concerns like actual missing commands though, of course.

Not this, but I do fairly often think assume I'm in vim when I'm not. `alias :q="echo NOT IN VIM!!!"`

My favorite one of these is typing ctrl-w (cut in emacs) in a browser tab as I am editing a bunch of text in a text box.

Well, cutting is called killing in Emacs...

iTerm gives you a warning if it thinks you just pasted in something malicious

I think it gives warning when you paste something ends with a `\n`.

I think my zsh does something to detect copy paste (and not execute the command till I press enter), or it could be iTerm, no idea.

I really do that a lot so I aliased 'q' to exit in shell.

The one I do is `git clone ` then paste in the repository URL from bitbucket, and end up with `git clone git clone https://....` I don't think that can be solved here though.

CTRL-u CTRL-v

I do. And I also write "vim vim thefile.txt" and stuff like that. Finally I've written a small shell function that corrects "gi tpull" to "git pull", because that happens at least once a day.

I just alias 'pull' to git pull, it's much nicer. Also 'push' and a few of the other most common ones.

Heh, for me ctrl-w means "extend selection to enclosing expression", which leads to the same issue in browsers.
