Problem with cat with PERL Substitute

system("cat FILENAME | perl -e 'while(<>) { print $_;}'");

system("cat FILENAME | perl -e 'while(<>) { $_ =~ s/XXX/YYY/g; print $_;}'");

First command works fine but second command gives the following error:

syntax error at -e line 1, near "{ =~"
syntax error at -e line 1, near ";}"
Execution of -e aborted due to compilation errors.


Any idea why? Smilie
