Re: Perl script w/o .pl extension broken on Ubuntu?

"psr.pl works fine, psr -> No command 'psr' found, did you mean:

Why do you think you can execute the program without using its full name? All the stuff you mentioned about changing your PATH and file permissions will be immaterial if you try to run a file that doesn't exist.

Have you tried renaming the script as psr and running that?

(You don't need the script file to end in a particular extension for Perl to be able to run it ...)

The way forward always starts with a minimal test.
