Creating shell script for cloning

Question

Hi,
I am cloning 11.5.8 instance. For copying of files from source to production I use rcp command. I want to create shell script that copies the files and lwhen it is complete send an email to my rediffmail account.
There are 2 problems:-
1. How to track if rcp commaind has completed.
2. How to send out an email. I tried to send an email using sendmail but it gave me an error "stdin: Value too large for defined data type".
Please help.
Thanks & Regards,
Neeraj

Hi Neeraj,
I'd suggest using the exit code from the rcp command to drive your email step. For most commands in Linux, and exit code of 0 indicates success, and in most shells, the environment variable $? stores the exit code of the most recent command. So, you could do something like this:
rcp source_files target_location
if [[ $? -eq 0 ]]
then
echo "Huzzah\!" | mailx -s "RCP from source to target successful" your_username@your_host
else
echo "Bummer.  Got exit code $? from rcp" | mailx -s "RCP from source to target failed" your_username@your_host
fiThe preceding advice is offered with three disclaimers:
1) I don't know which shell you're using (ksh, bash, csh?) -- my code snippet assumes ksh, but the principles should be the same in any shell
2) My morning coffee has not yet taken effect, so I may be completely wrong about something important :-)
3) The code above is untested, and will probably not work in any shell without modification.
Despite all that, hopefully this will put you on the right track.

John P.
