You would use the options -b and -bext='/'

perltidy -b -bext='/' foo.pl

Taken from the man page

Make sure you don't have -st provided or the -b and -bext options do nothing; this was actually my problem.

It looks like perltidy has a native solution. Not all programs do. The sponge utility can be used to achieve in-place editing for programs that don't natively support it.

prog file | sponge file

@JRFerguson, Kinda. It links to the other answer. I wanted to acknowledge that this might not be the best answer in this specific case, but it might help others. – ikegami Jun 05 '20 at 20:09
