The output from changing your environment with set -x will be written to Standard Error, file descriptor number 2. If you are doing this within a script and want to capture it to a file, you can:-
Code:
myscript 2>trace_file
If you want to capture Standard Output from the script along with it, you can:-
Code:
myscript >trace_file 2>&1
.... with the 2>&1 directing it to the same as Standard Output. Some shells may have a problem if you try:-
Code:
myscript >trace_file 2>trace_file
and you only get one of the other output saved to the file.
I hope that this helps,
