[Help-bash] BASH_XTRACEFD on stdout

[Matthew Lenz]

I wasn't thinking and thought:

BASH_XTRACEFD=1
set -x
commands

wouldn't bite me, but of course it did (piping between commands)

I switched out to the following:

exec 4>&1
BASH_XTRACEFD=4
commands

The reason I'm doing this is because I have a cronjob that I'd like to do
the following:

script.sh 2>&1 >> logfile | tee -a logfile

This puts the stdout, debugging and stderr in my logfile but also allows
stderr to flow through in a mail notification.

It appears to not cause problems.  Any reason to think otherwise?
