Need little script to send out email

Shell Programming and Scripting

Hi Scripters, good day.

bash-4.2# df -g /apps/prd
Filesystem      GB  blocks Free  %Used    Iused  %Iused Mounted on
/dev/xxx     64.00         4.35    94%  1269284      8% /xxx
bash-4.2#

I was wondering if there is a script when the usage of the mountpoint above hit 98%, email would be sent to a specific mailbox? Thanks in advance.

Almost certainly, yes. Look into the links at the lower left of this page, under "More UNIX and Linux Forum Topics You Might Find Helpful", or search these forums for "almost full".

I think you can just set a cronjob to run at your preferred interval.

mine is running on solaris 10 hence command might varies.

20 * * * * df -h | tail +2 | awk '{if ((length($5) > 3) || ((length($5) > 2) && ($5 > 98))) print $0}' | mailx -s "Email Subject" <email address>

You should be able to simplify that awk code a little bit to just:

20 * * * * df -h | tail +2 | awk '($5 + 0) > 98' | mailx -s "Email Subject" <email address>

but on a Solaris/SunOS system, that would be:

20 * * * * df -h | tail +2 | nawk '($5 + 0) > 98' | mailx -s "Email Subject" <email address>
