in thread how to run this script

when i do ./filename it gives error bash: ./ Permission denied
You probably need to give your file execute permissions, like:
chmod 777

Also, conventionally, the .pm file name suffix is reserved for Perl module files (see package). It is more common to use the .pl file extension for scripts.

    chmod 777

    Far too permissive!

    That gives every man and his dog permission to run, modify or even delete the script, if they are able to browse to the directory containing it. Much safer would be

    chmod u+x

    We see, and have to try to fix, the chaos that ensues when someone does an ill-considered

    chmod -R 777 /some/path/with_lots_of/sub-directories

    and it is a practice strongly to be discouraged.
