it is a parody seemingly, according to @gandalf_der_12te@discuss.tchncs.de’s comment

It seems to be a meme/parody instance

Probably a meme instance / parody

No, you need to do unrm -unrf /

I like ls -Ap, the -p option is convenient, it puts a / at the end of names if they’re directories. -A is like -a but doesn’t show . and ..

-l is sometimes useful, but a bit cluttered and less readable (at least to me, maybe it wouldn’t be if I were used to using it)
