script to return value
I have 3 scripts

script A - wrapper script to disguise invoker true identity

script B - perform database operation and return a value (either W/H)
-> return value by echoing the result

script C - use script A to mask as the database owner then invoke script B to retrieve the value
-> /sys1/proclib/wrapper.sh dbadmin status.sh

I want to store the result in a variable, hence, status=`/sys1/proclib/wrapper.sh dbadmin status.sh`
but the result that I got back is actually "[YOU HAVE NEW MAIL] P" instead of just "P".

I found out that when script A is invoked, it would automatically echo "[YOU HAVE NEW MAIL]" to stdout.
All I want to be able to get the result from script B, anyone can help? Thanks!

Just trying to get what your on about...

You run Script C, which runs Script A which runs Script B
How Script B echos either a W or a H when complete.

And you want to know this when script c ends....correct????

If thats the case try this (It may need testing....as there are other ways to trap stuff)

Inside the scripts try this

set a variable to the running of each script.

ie

ScriptC
end_scriptA=`/path/to/scriptA`
echo $end_scriptA

ScriptA
end_scriptB=`/path/to/scriptB`
echo $end_scriptB

There are better ways by using the $?
