Shell Programming and Scripting

Hello Everybody,
thanks in advance for spending some time in my problem.
My problem is this:
I want to call a java-Programm out of my shell skript, check if die return code is right, and split the output to the normal output and into a file.

The following code doesn't work right, because in the if construct it checks if de 'tee' command did work.

could you igamine what solution could solve my problem? (the java command itself works, the stars are only for anonymize)

thanks a lot

This should work, though the processing would happen before displaying the output:

Code:

if java ... > TEMP.FILE; then
    # Process success
fi
cat TEMP.FILE | tee -a $PathToLog
rm -f TEMP.FILE

Or this would keep things in order:

Code:

java ... > TEMP.FILE
result=$?
cat TEMP.FILE | tee -a $PathToLog
rm -f TEMP.FILE
if [ $result = 0 ]; then
    # Process success
fi

Or, if the processing produces no output, you might do this:

Code:

if java ... ; then
    # Process success
fi | tee -a $PathToLog

This works - after a first test - fine for me, the 2 other solutions don't fit my needs for this script, but maybe i'll use them another time . Thanks a lot!

After some own research today, i came across this solution:

Code:

set -o pipefail

if ( java .... ) | tee -a $PathToLog
then  # Process succes
fi

Can you think of what solution of these two would be the best one?

thanks and greets
