Convert from Csh to Perl

Hi ,

I am trying to convert the below code embedded in a csh script to Perl.
Can any expert give me some advice on this ?

sed -n ''"$start_line"',$ p' $tester_dir/nfiles_extracted.txt|cut -c1-4,6-|/bin/perl $test_summary/compare_for_all
_Duts.pl|sort > $tester_dir/nfiles_extracted1.txt
