Question

I have the following script to check if a NFS mount is currently mounted on the server :

#!/bin/bash
$targetserver=192.168.3.1
commandline="mount | grep '$targetserver' | wc -l"
checkmount=`$commandline`

if [ $checkmount == "1" ]; then
  echo "Mounted !"
else
  echo "Not mounted"
fi

But it seems that my checkmount is not returning anything.

What am I missing here ?

Answer 1

This should work better.

#!/bin/bash
targetserver="192.168.3.1"
commandline=$(mount | grep "$targetserver" | wc -l)

if [ $commandline -gt 0 ]; then
  echo "Mounted !"
else
  echo "Not mounted"
fi

You could shorten it down though, using $?, redirection and control operators.

targetserver="192.168.3.1"
mount | grep "$targetserver" > /dev/null && echo "mounted" || echo "not mounted"

Depending on system grep /etc/mtab directly might be a good idea too. Not having to execute mount would be cleaner imho.

Cheers!
