in reply to the end of a word

perldoc -f chop

for when you know you don't want the last letter

perldoc -f tr

for when you want to get rid of certain characters no matter where they appear, example: $directory =~ tr/\]//

perldoc perlre

for when you need to do some fancy reg ex substitution stuff to get at real specific stuff like remove a specific character at the end of a string, example: $directory =~ s/\]$//
