above commands showing error when run with back quotes in perl script

What command are you trying to run?

You will have to use escape characters to use them

hi dinjo,

can you please be more specific as to how to use escape sequences to make this command work in perl

Just a example.See the backslash

/usr/bin/awk \'{ if (\$1 > 85) {print \$1 \$4\ } } \' | grep -v \"Name\"

don't need to use the system find command. you can use Perl's module File::Find.

yes use the File::Find module
anyway, that's the way you can get your above command to work without great masking:

$a='find . ! -user 0 -exec ls -l {} \; | awk \'{print $3,$9}\'';
system ("$a");
