I was passed someone else's homework which included describing what certain Bash commands do. I've a fair bit of experience and I can't imagine why this one would be useful, can you think of any use for it?

(find -type d) | grep public | tr './p' ' '

shield bash 🛡💥

Find directories called public, and rename to './p'

or I'm looking at this all wrong and should get another coffee before punching that into a terminal and regretting every moment of it 😂

@C0D4 The tr command here replaces every occurence of any of the characters dot, slash and p with a space.

(find -type d)

() For subshell.

grep public

search in result for public.

Highly inefficient and fragile, as output of find is parsed directly.

tr replaces chars as @Ibfalvy explained.

All in all, total bleh.

Note:

./public/test becomes ublic test

The subshell is to dump all content before grep and tr takes place.

Hence grep works on the whole output of the find command.

@IntrusionCM I know, my question was why this would ever be useful.

@lbfalvy

Easier spotting of interesting substrings.

I'd guess it's a way to "highlight" the substring.

Maybe to find out which subfolders exists in an webserver directory to determine where the assets are stored.

I'll do sometimes the same, just in a more eloquent way.

Helps filtering out non interesting stuff. XD
