in reply to Running a backticks command in a CGI script

G'day Cody Fendant,

Yes, I can make that silently fail too:

$ perl -e '$result = `foobar`'

But I start getting feedback if I ask for it (i.e. with strict and warnings):

$ perl -Mstrict -Mwarnings -e '$result = `foobar`' Global symbol "$result" requires explicit package name at -e line 1. Execution of -e aborted due to compilation errors.

OK, let's fix up that one from strict:

$ perl -Mstrict -Mwarnings -e 'my $result = `foobar`' Can't exec "foobar": No such file or directory at -e line 1.

Now this one from warnings which clears all errors:

$ perl -Mstrict -Mwarnings -e 'my $result = `ls`'

Given you're working in a CGI environment, you may find the fatalsToBrowser feature of CGI::Carp to be useful.
