Proc::SafeExec provides an easy, safe way to execute external programs. It replaces all of Perl's questionable ways of accomodating this, including system(), open() with a pipe, exec(), back-ticks, etc. This module will never automatically invoke /bin/sh. This module is easy enough to use that /bin/sh should be unnecessary, even for complex pipelines. WWW: http://search.cpan.org/dist/Proc-SafeExec/
