Perl way of using cut,grep,uniq [closed]

I am running a Perl script inside a Perl script, and the output of the script is something like this

# aAM axac: cmt /tm9/raaqHRW /myqq1fqq1er/angyvqnqth/rmn/cqqqa/newfqq1er/111111111/ty9a1.1.e.1234567891008547.ahqva

I need to get an output like this

tm9/raaqHRW /111111111/ty9a1
tm9/raawV9h /111111111/ty9a4
tm9/raaaRX6 /111111111/ty9a7

I am currently writing the output of the script to a file and doing as follows,

grep "cmt /tm9" output_file | cut -d'/' -f2,3,9,10 | cut -d '.' -f1 | uniq

Is there a Perl way to do this?

perldoc perlrun will teach you how to fish:

-n to read in a file line by line
-a to split each line into @F (and emulate cut)
list slices to access items stored in @F to emulate cut's -f flag
regex conditional to emulate grep
use hash keys to emulate uniq
