script for checking if a drive is mounted

Soulja1 · 05-07-2007, 03:01 PM

i was wondering if anyone knows how i can make a script to check if a drive is mounted or not. The reason for the script is i want to automate my tar backs but my backups go to a samba mounted drive. I however am on a notebook and sometimes i am not on the network with the samba share, so i can't have my backup program run during this time.

well just run "mount" and grep for the name of the share you're interested in. you could run that and check the value of $? after it, or just use test to see if the output is nonzero

[ "$(mount | grep sharename") ] && script_to_mount_share

Code:

#!/bin/ksh

mounted=`df | grep "/mntpoint"`

if [[ mounted != "" ]] ; then
   tar cfv /mntpoint/blah.tar blah
else
   print "backup drive not mounted."
fi

Replace /mntpoint with the directory where you mounted the backup drive in. Also replace blah.tar and blah with the name of the tarball and the directory you want to backup.
