Perl TipsHere are Perl tips. IndexHow can I set the module path for Perl ?This is a real pain if you are not a root so that modules cannot be put in the default place /usr/lib/perl5 .....First check the module path by (note that RedHat installs it in /usr/lib/perl5) $ perl -e 'print "@INC\n"' /usr/lib/perl5/5.8.0/i386-linux-thread-multi /usr/lib/perl5/5.8.0 /usr/lib/perl5/site_perl/5.8.0/i386-linux-thread-multi /usr/lib/perl5/site_perl/5.8.0 /usr/lib/perl5/site_perl /usr/lib/perl5/vendor_perl/5.8.0/i386-linux-thread-multi /usr/lib/perl5/vendor_perl/5.8.0 /usr/lib/perl5/vendor_perl /usr/lib/perl5/5.8.0/i386-linux-thread-multi /usr/lib/perl5/5.8.0 One way is to set the environmental variable PERL5LIB. csh: $ setenv PERL5LIB where_pathbash: $ export PERL5LIB="where_path" Another way is to point the module location in perl script itself. use lib 'where_path'; How can I get a new module from internet?I was told by a perl lib not to be able to find Text::Format module. I used CPAN to do this job. # perl -MCPAN -e shell /usr/lib/perl5/5.8.0/CPAN/Config.pm initialized. CPAN is the world-wide archive of perl resources. It consists of about 100 sites that all replicate the same contents all around the globe. Many countries have at least one CPAN site already. The resources found on CPAN are easily accessible with the CPAN.pm module. If you want to use CPAN.pm, you have to configure it properly. If you do not want to enter a dialog now, you can answer 'no' to this question and I'll try to autoconfigure. (Note: you can revisit this dialog anytime later by typing 'o conf init' at the cpan prompt.) Are you ready for manual configuration?
