hi,

i read in the docs https://www.howtoforge.com/tutorial/...-ubuntu-16-04/

apt-get install nagios-plugins* cpanminus

Install these Perl modules with the cpanm command:

cpanm Net::SNMP
cpanm Time::HiRes
cpanm DBI


i don't understand what is cpanm and why to use it
thanks for your help

regards
