Help me add Error Handling to my script
Hi all,

I have some sections of a script that I am trying to add error handling to. Basically if it returns any error, just continue. This is for a deployment script that i am writing to assist in the deployment of scripts out to other systems.

At the top of my KSH script i added this function

Code:
on_error_continue()
{
if [[ $? -ne 0 ]]; then
print "$1"
#exit $?
continue
fi
}

This is the code i am currently using, but the error handling doesnt seem to be working.

Code:
for hostname in cat hostfile
do 
rcp $DEPLOY $hostname:/var/tmp/$TYPE
on_error_continue "Could not remote copy"
rsh $hostname "nice -n 39 ksh /var/tmp/$TYPE &"
on_error_continue "Could not mount the NAS"
done

Can someone point me in the right direction?

NAME

       script - make record of a terminal session

SYNOPSIS

       script [-a] [filename]

DESCRIPTION

       The  script  utility  makes a record of everything printed on your screen. The record is written to filename. If no file name is given, the
       record is saved in the file typescript. See WARNINGS.

       The script command forks and creates a sub-shell, according to the value of $SHELL, and records the text from this session. The script ends
       when the forked shell exits or when Control-d is typed.

OPTIONS

       The following option is supported:

       -a	Appends the session record to filename, rather than overwriting it.

NOTES

       script places everything that appears on the screen in filename, including prompts.

WARNINGS

       script  can  pose  a  security risk when used in directories that are writable by other users (for example, /tmp), especially when run by a
       privileged user, that is, root. Be sure that typescript is not a link before running script.
