All sky covered in clouds, except to the East. No chance of witnessing the stars shooting around. Still 25°C. Bah.
dash or ash, very nice POSIX Sh compliant shells:
$ ./foo.sh
./foo.sh: line 5: [: bar: integer expression expected
So the lessons here are twofold:
- Always use
shellcheck to check your shell code- Never use Bash or rely on Bash(isms). Always prefer POSIX Sh

So this works:
$ bash -c 'set -u; bar=1; foo=$bar; if [[ "foo" -eq "bar" ]]; then echo it matches; fi'
it matches
Without the misleading quotes:
$ bash -c 'set -u; bar=1; foo=$bar; if [[ foo -eq bar ]]; then echo it matches; fi'
it matches
As does this:
$ bash -c 'set -u; bar=1; foo=$bar; if (( foo bar )); then echo it matches; fi'
it matches
What the person originally meant was what bender said:
$ bash -c 'set -u; foo=bar; if \n]; then echo it matches; fi'
it matches
It’s all rather easy once you’ve understood it … but the initial error message of the initial version can be quite unexpected.=

But I'm wondering how you discovered it a week later. Are you somehow regularly checking complete recent feed histories?
This project is verrrry alpha. all the configuration is literally in the code.

-eq is for numerical comparation only. Weird error message, though. Tells something about the implementation.
h
bash -c 'set -u; foo=bar; if [[ "$foo" = "bar" ]]; then echo it matches; fi'

bash -c 'set -u; foo=bar; if [[ "$foo" = "bar" ]]; then echo it matches; fi'
eq is for numericals.
But sadly they’re full of pitfalls. Pitfalls everywhere you look.
Today, a coworker – who’s highly skilled, not a newbie by any means – ran into this:
$ bash -c 'set -u; foo=bar; if \n]; then echo it matches; fi'
bash: line 1: bar: unbound variable
Why’s that happening? I know the answer. Do you? 😂
Stuff like that made me stop using shell scripts at work, unless they’re just 4 or 5 lines of absolutely trivial code. It’s now Python instead, even though the code is often much longer and clunkier, but at least people will understand it more easily and not trip over it when they make a tiny change.=
