http://www.thegeekstuff.com/2008/09/how-to-install-perl-modules-manually-and-using-cpan-command/
If you are using Red Hat Linux then use up2date command to install most common modules:
# up2date module-name
Use following command to list all supported modules:
# up2date --showall | grep -i 'perl'
OR use yum command under CentOS/RHEL 5/Fedora core:
# yum list available 'perl'
If you are using Debian Linux, try to use apt-get command to install common perl module. However following is the recommended way to install a perl module.
A) Start CPAN Shell:
# perl -MCPAN -e shell
B) Install a perl module:
At cpan> shell prompt install module using install module::Name command. For example install module called MIME::Lite:
# cpan> install MIME::Lite
Alternatively, try out the following command:
# cpan -i MIME::Lite

# Short Tip: egrep – using grep with more than one expression
-------------------------------------------------------------
The multiple arguments you are searching for a passed to egrep separated by pipes. For example, if you want to grep the output of lspci for all audio and video controllers, the correct command is:
Tip: Usando egrep con más de una expresión
A veces necesitamos filtrar más de una expresión en un output y el filtrado con grep nos va pedir que corramos el comando más de una vez para ver todos los resultados, así:
lspci | grep -i audio
lspci | grep -i vga
Se puede ver todos los resultados de una sola vez con egrep, así:
lspci | egrep -i 'audio|vga'
00:02.0 VGA compatible controller: Intel Corporation Core Processor Integrated Graphics Controller (rev 12)
00:1b.0 Audio device: Intel Corporation 5 Series/3400 Series Chipset High Definition Audio (rev 06)
El parámetro "-i" es para que egrep busque sin distinguir mayúsculas.
Claro, es más escalable, ya que podemos buscar una gran cantidad de patrones simultáneamente:
lspci | egrep -i 'audio|vga|ethernet|network'
00:02.0 VGA compatible controller: Intel Corporation Core Processor Integrated Graphics Controller (rev 12)
00:1b.0 Audio device: Intel Corporation 5 Series/3400 Series Chipset High Definition Audio (rev 06)
