TIMTOWTDI A couple useful examples have already been offered. Here's mine: perl -MSome::Module -e '' If the module is installed, it'll just quietly end. If not, it'll give you an error explaining how the module is missing. Examples follow. Technically (as you may guess from the mention of BSDPAN), this is a FreeBSD system rather than a Linux system, but the principle is the same. input: perl -MGetopt::Std -e '' no output (module present) input: perl -MGetopt::Wakka -e '' output (module not present): Can't locate Getopt/Wakka.pm in @INC (@INC contains: /usr/local/lib/perl5/5.8.8/BSDPAN /usr/local/lib/perl5/site_perl/5.8.8/mach /usr/local/lib/perl5/site_perl/5.8.8 /usr/local/lib/perl5/site_perl /usr/local/lib/perl5/5.8.8/mach /usr/local/lib/perl5/5.8.8 .).
