Hi

I'm looking for a perl script to send a mail, if the linux partition is quite full, for example 95% used capacity.

    You want to look at Nagios. You get monitoring, and thus warning, before the file system falls over.

    Hello,

    A typical shell script solution would be

    # df /partition | perl -ne 'exit 1 if (/(\d+)%/ and $1 < 95)' && echo "Partition full in $(hostname)" | mail -s "$(hostname) - Partition full" xx@yy.com

    But If you want a pure perl solution, then take a look at Filesys::Df and Mail::Send

    Other option, if you need a more complete soltution, is using a monitor system like nagios (which was recommended in first comment), munin, or zabbix

    Also, please read How do I post a question effectively?.

    PD: Updated to be one perl line script
