Doesn’t seem to work

1: Can’t download the file; had to copy from browser and past it in vi
2: not enough instruction how to set it up and what it needs to run
3: no instructions on how to run it and pass parameters to it.
4: Doesn’t which perl version it needs
I tried to run it and I got following line
I do have perl installed
nagios@wlnagios:~> which perl
/usr/bin/perl
nagios@wlnagios:~>

nagios@wlnagios:~> ./check_cpu.pl
