Script Debugging

[Nikee Reddy]

Hello,

I have included the following lines in my script to debug it. Unfortunately the debugging is not working.

#!/bin/sh
set -x

Thanks,
Nikee

could you possibly include the actual script or at least the 10-15 lines following the set -x command, so that more educated gusees can be done ?

Hi,

You could add a v:

#!/usr/bin/ksh
set -vx
.........
set +vx

Regards,

Gideon

Well, that should work. About all I can suggest is that you look for and install the latest cumulative POSIX shell patch for your OS release.

If you added set -x, then you will see your script traced. NOTE: all trace output goes to stderr, not stdout. So if you saved stdout in a file, the trace output went some other place. Are you running this script from cron or at? If so, the debug trace output was emailed to the user running the script. To get evrything sent to stdout, you can trace your script without set -x like this:

sh -x your_script > your_log 2>&1

One additional note: functions will not be traced without explicitly adding set -x in each function. Note also that set -v also add the original lines of the script mingled in with the trace.
