Hey this doesn’t work : first solution “ls -al” which I use all the time to list directories was rejected in the second question I used awk and was rejected it expected grep

I think a beginner could be doing it right but then be told they are wrong as you aren’t evaluating actual commands

Best would be to like actually run it* and then check solutions out with awk that it pattern matches

* aka give me a shell ok worth a try lol xD

Edit: also I was expecting something a bit more challenging (also that is correct) to like exercise the brain for those of us that use shell (this is hacker news) something that takes a few minutes and isn’t just commands used all the time

"ls" shows only visible files whereas "ls -a" also displays those starting with a dot. Given the question doesn't that make your answer the correct one?

[zenoprax]

`la -A` will also show hidden files but excludes the "." and ".."

I prefer that way in theory but a capital "A" is not as quick/easy to type.

[derrida]

It accepts ls -a as and answer and ls -l but not ls -al

[Retr0id]

It does seem to actually run the submitted commands, and awk is there.

Second question

> awk '/^laugh/ { print $0 }' night-before-christmas.txt

[aidenn0]

Get rid of the caret and it works; it wants lines with laugh, not lines that start with laugh,

Ah cheers thanks, my stupid! (And what's worse - wasted some others attention and even thought what someone took time to create was at fault!) However thankful for kind directness there.

it also doesn't accept the find command.
