excluding "/" from filesystem check script

JLee_1 — Fri, 16 May 2008 14:29:56 GMT

Hi -

I'm using a shell script to monitor filesystems and alert via email when they reach a certain capacity. I'm trying to exclude the root filesystem with a 'grep -v', but when I do it's exluding all filesystems and I don't get alerted on anything. I was wondering if someone could check the syntax on this and maybe point me in the right direction. Thanks in advance for your help.

# Main body
#----------

if [[ -n `bdf | grep -v -e / | grep -e "8[5-9]%" -e "9[0-9]%" -e "100%"` ]]
then
bdf | grep -e "8[5-9]%" -e "9[0-9]%" -e "100%" | \

Hi,

if you exclude '/', then you exclude everything under '/' - and ALL is under '/'!
Maybe this works like you want - eclude the logical volume of '/': bdf|grep -v -e lvol3

(lvol3 is in my case the logical volume of '/' - but this is also the standard)

Hi:

If you want to use 'grep' to exclude the '/' mountpoint, do:

# bdf | grep -v "/$"

...the '$' anchors to the end of the line.
