Do you need POSIX compability?

If not, use bash-isms without shame

But call it a bash script then! Remember: #!/bin/sh is run by all kinds of shells; consider them POSIX. Bash is #!/bin/bash.

Uhm, yes. I noted exactly that as well.

Also bash is not always at /bin/bash :-)

[–] MonkderVierte@lemmy.zip 2 points 1 day ago* (last edited 1 day ago) (1 children)

Yeah ok, /usr/bin/env then.

Edit: Or /bin/sh (oold convention) and check for bash.

Well, that won't work on openbsd (and probably freebsd), because non-default.stuff lands in /usr/local/bin.

For Linux you should be fine though.
