pearl -p -i -e "s/$ARGV[1]/$ARGV[2]/g" `grep -i -l $ARGV[1] $ARGV[0]`

Learning perl is challenging. Pointless, but challenging. Why don't you try the Structure and Interpretation of Computer Programs instead?

>>2954901
kinda this.
as much as i don't like python i feel like it's a better scripting language to learn if you're set on learning one.

>> No.2954918

OP, unless you're doing it for school or work, I don't see any reason why you need to learn PERL.
