CPU & Memory how to include a text pattern in system function in PERL

Code:
system ("ls -la $filename | awk '\$1~ /^-......r../ {print \$9}'");


i know for displaying text in awk command one needs to put it in double quotes "" but here how to do that.. when we are executing awk in system command (which already has double quotes in the start and end)
