Pretty much anything longer then a throwaway one liner I write in python.

Would be cool if python had a pipe operator though.

The back ticks in ruby is pretty ergonomic too. Wish python had a simpler way to run commands. Kind of tedious to look up subprocess run arguments and also break things up into arrays.

You can always set shell=True and pass in an entire command line as a string, but… don’t do that. It seems really nice until the first time you get the shell escaping wrong, and then it’s something you tend never to do again.

For example,

  subprocess.run(“rm -rf ~/ some file”, shell=True)

and

  subprocess.run([“rm”, “-rf”,  “~/ some file”])

have significant different behavior.

What is the difference in behavior? They both look like they would delete the user's home directory. I assume the latter would try to delete a directory literally named with a tilde instead?

		The latter passes each item in the list into the child processes’s argv, as-is, without the shell parsing them. That means this would delete a single item named “~/ some file”, spaces and all, instead of three items named “~/“, “some”, and “file”. Edit: I’m typing this on my phone, so brevity won over explicitness. The latter probably wouldn’t expand ~. Imagine a file named “/home/me/ some file” for a better example.

nushell (https://www.nushell.sh/) is essentially perfect for this use case! i use it rather than posix(y) shells for most projects where id normally reach for python.
