I editted my original post after your first post, and clarified the two things I'm trying to do.Quote:
Code:
#!/bin/ksh
touch test.file
AFTERLOG=./$$.after.log
LOG=./tmp.log
(
echo "Hello world"
echo "1st echo return code is: $?" > "$AFTERLOG"
ls -ltr test.file
echo "Return code is: $?" >> "$AFTERLOG"
echo "Goodbye world"
echo "2nd echo return code is: $?" >> "$AFTERLOG"
) 2>&1 | tee "${LOG}"
cat "$AFTERLOG"
rm -f "$AFTERLOG"Thanks ... I think what I found with the exec 5>&PIPE seems to work more consistently.
And it seems from the responses, that another (cleaner) option probably doesn't exist.
Don't want to take any more of your time
Sorry for confusion, thanks for help. I think I have something working, and I think I understand what's going on. Cheers!|

OK, that's good... so I try:
