TIL you can use "for i in <glob>" in bash(posix?)

for i in /opt/local/bin/*; do echo $i; done

rather than

for i in $(ls /opt/local/bin/); do echo $i; done

I can't believe I've been typing unnecessary $() for decades.

(aside: I can never remember where the ; go)

@riffraff for i in do do do; do echo $i; done

@riffraff you can put a ; after the command “do” if you want, it’s redundant…

for i in do do do; do; echo $i; done

[andrewg@mastodon.ie]

@riffraff as opposed to `for i in do do do; echo $i` of course 🤡

@andrewg something's off with my console, I typed do do do do do do do do do and a saxophone by Ronnie Ross started playing
