Need a script for the below actions

Sreer — Fri, 14 Oct 2011 18:18:15 GMT

Hi Gurus,

I need to develop a script for the below scenario.

My scripting skill is not so good..

I need to have a script for the below setup.

1 - check if /home/nullecte is defined in local /etc/auto_home

     If no, send an alert ("/home/nullecte not defined on host ...") by email to :
   sree@abc.com
  and then, exit script

2 - check availability of node "nullecte"
  If no, send an alert ("/home/nullecte not available from host ...") by email to :
   sree@abc.com
  and then, exit script

3 - check if there are differencies between
  /etc/auto_home and /home/nullecte/TechD/ref/auto_home

  If no -> nothing to do
  If yes -> replace local /etc/auto_home by ref (/home/nullecte/TechD/ref/auto_home)

4 - check if there are differencies between
  /etc/auto_home and /home/nullecte/TechD/ref/auto_home

  If yes -> send an alert ("auto_home inconsistency on host ...") by email to :
   sree@abc.com

could you please help me to get a script for this?

Many thanks in advance.

Hi:

Help or write? The best way to learn how to do something is to try! Here's some pointers, comment by comment:

#1 Consider 'grep'. For example, 'grep -q nullecte /etc/auto_home' will return a zero exit status if a match is found.

#2 Define "availability". Do you mean ping-able? Do you mean a particular process is running?

#3 'diff' is your friend. Read its manpages. As for replacements, look at 'sed', in the general form of 'sed -e '/this/that/' infile > outfile'. By the way, what do you mean by " ref (/home/nullecte/TechD/ref/auto_home)"?

#4 'diff' again

As for sending mail, simple alerts can be composed thusly:

# echo "I want help" | mailx -s "HELP!" sreer

...where "I want help" is the body of the message and "HELP!" is the subject and you are the recipient.

If everything you want to say is in the sublect line, do:

# mailx -s "HELP HELP HELP" sreer < /dev/null

Regards!
