Catching all Exit Codes
I have a Unix Script that has several exit in the middle. each returning seperate
exit codes.

I have to catch all the exit's and perform an operation say "Mail the status code" before the actual code completes.

How can i do this in KSH ?

Introduce a function to catch all the exit codes.

Something like

Code:
 
EXIT_CODE=""

function assembleExitCode
{
EXIT_CODE="${EXIT_CODE} $@"
}

At every place where you are looking for an exit code, invoke the function as
Code:
assembleExitCode $?

At the end of the code,

Code:
if [[ x"$EXIT_CODE" != x ]] ; then
echo "Mail status"
fi ;

Try this
case $? in
1) echo "Exit message1";;
2) echo "Exit message2";;
.
.
.
