I know that there are use cases for [ ] over [[ ]]. There have to be. Why in god's name would [ ] exist if there wasn't a reason to use it over [[ ]]? I'm obviously the one in the wrong by only ever using [[ ]], because [ ] would definitely be better in some type of situations that I'm just not seeing clearly. Right???

I believe the reason is that bash is backwards compatible with sh and sh only has [ ], not [[ ]]

[–] float@feddit.de 6 points 1 year ago

[ is a binary (sometimes a symlink) in /usr/bin. It's /usr/bin/[ 🤓

Solution: fuck backwards compatibility and use fish

[–] twelvefloatinghands@lemmy.world 8 points 1 year ago

Fish might be good for interactivity, but in terms of scripting, just go straight to python. It's not worth it.

Fish is starting to get more POSIX compliant as of late, the error redirect is no longer ^ /dev/null but 2>/dev/null

[[ is not a POSIX shell feature.
