Correct would have been this one
Code:
[[ ! -z  `mount | grep -i ip` ]] &&  echo "ip is mounted" || mail -s "ip not mounted" someone@somwhere.com
^ good one-liner code! thanks

I have named the text file as "test.log" and i thought it would keep adding - one line "Disk is mounted" instead of replacing. Pls help in getting threaded log file..
ex:line 1. disk is mounted $date
line 2. disk is mounted $date
instead of one single line - disk is mounted $date.

^ @ O.S black hole -> lol , neat explanation though! thanx!

Use ' >> ' instead of ' > ' to append line to test.log file

Hey rod,

You can also check out this script, if it helps you:

varcheck=`mount | grep “/sda1″`
if [[ ${#varcheck} == 0 ]]
then
#Attempt to mount
`mount /dev/sda1 2>/dev/null`
varcheck=`mount | grep “/sda1″`
if [[ ${#varcheck} == 0 ]]
then
echo “Could Not Mount /dev/sda1″ | mail -s ‘External Backup – Could Not Mount Drive’ $MAILLIST
exit
fi
fi
