if you are so smart, write a bash script that converts every filename in a directory to be in lower case, and all instances of space replaced with underscore, and all instances of brackets and parenthesis to be omitted
for example,
>[SubsPlease] Machikado Mazoku S2 - 01 (1080p) [43AAE859].mkv
becomes
>subsplease_machikado_mazoku_s2_-_01_1080p_43aae859.mkv

Do it yourself, OP.
You should at least know some basic Perl.

Just make github copilot do it for you. The Any Forums personal army has been automatic yourself

i'm not doing your homework for you
also nakadashi mikan

for f in *; do new_name="$(echo "$f" | tr 'A-Z' 'a-z')"

Something like that, go learn your shell you dumbass.

nakadashi mikan

bruh this is trivial

>learn your shell
bash can do all the replacement with like 3 parameter expansions, without piping shit around to external executables

for f in *; do mv "$f" "$(echo $f | tr '[:upper:]' '[:lower:]' | tr ' ' '_' | tr -d '[{}()]')"; done

>writing a non portable script

>bash
No.

Are :upper: meta characters POSIX?

i made something similar in php for a database. str_replace blah blah blah then fput csv

btw OP developers are expensive. don't ask us to do it for you. read the manual of the language youre planning to use and do it yourself.

Yes, [a-z] is not equivalent to [[:lower:]] in some locales

A smart person wouldn't waste their time with that gay shit when programs that can do it and more already exist.

echo "$1" | sed 's/\[//g;s/\]//g;s/(//g;s/)//g;s/ /_/g' | tr 'A-Z' 'a-z'

$(ls | sed 's;^;mv ' | tr 'A-Z_' 'a-z ')

yeah that might work idk im not testing it

filename manipulation is literally impossible without null delimiting gnu extensions. go fuck yourself you massive discord npc retard and get some opinions of your own
just to spite you I solved op's homework using those bashisms you hate so much
a='...' a="${a//[[]()]}" a="${a// /_}"; echo "${a,,}"
