[SOLVED] Script

poseidonsurf · 02-27-2013, 08:41 PM

I made a script for mounting but what how would I post that it has mounted sucessfully in the script. I want to echo "Mounted all sucessfully" and "One or more didn't not mount sucessfully. It's pulls from my fstab. Any help would be great! Thanks!

Hi,

the mount command should return with a non zero status if there were errors. Eg.

Code:

#!/bin/sh
mount -t ext4 /dev/foo /amountpoint
if [ "$?" = "0" ] ; then
  echo "Sucessfully mounted /dev/foo at /amountpoint"
fi

If this doesn't help, perhaps you could post your script and explain in more detail what you are trying to do.

Generally difficult to assist without seeing the code as you may have loops and or read statements to deal with that could cause output to not display.

Indeed, better to see what you've tried so far. Anyway, using a loop you may want something like this:

Code:

while read device mount_point
do
  mount $device $mount_point || NO_MOUNT=1
done < list_of_devices_and_mount_points

[[ -z $NO_MOUNT ]] && echo Mounted all successfully || echo One or more didn't mount successfully

The script is:

Code:

#!/usr/bin/expect

spawn su -
expect "Password: "
send "Password\r"
send "mount -a\r"
interact

It's a small script but obviously to do all the mounting it needs to be in root. After mount -a, if it successfully mounts without an error I want to echo "Mounted Sucessfully" if didn't mount all, I want it to echo "One or more have not sucessfully mounted". Thank you in advance for your help.

Hi,

it is *REALLY* bad idea to use expect like that to provide the root password.

Anyway as we've already mentioned mount will exit with 0 status if there were no problems, and non zero otherwise. We have also already provided example code for this.

Why on earth are you doing such a thing?
If it's in your fstab just:

sudo mount /blah

It's like using a drill as a food mixer when you have an electric whisk in the cupboard.

Thank you everyone for you quick replies. Evo2 - I thought I needed root to mount all drives? Maybe not. I will see. Is there a way to put a count down before the screen exits?

You don't need root to mount drives that have the flag "user" in /etc/fstab. Also any drive that does not have the "noauto" flag will be mounted automatically at boot (and whenever "mount -a" is run. Have a look at the mount and fstab man pages.

Sorry, I don't understand the question.

It states only root can perform mounts.

I figured it out. Thank you though.

Would you like to share with the rest of the class so others can learn from what you found?

I used sudo instead
