Please show us what you've tried, and tell us in which way it doesn't work.

You have to be careful which variables you interpolate, and which you don't: 

my $file = 'stuff';
system qq[grep 'DataDictionary' $file | awk -F'<pciOFACViolation>' '{p
+rint \$1}'|...];
#                               ^ interpolate                         
+      ^ don't interpolate
