Running this command turns shell tracing and shell verbose debugging on or off. Not only does it do that, it also uses your terminals builtin method of setting colors to make debugging much easier.
It looks at the current shell options contained in the $- special bash variable and that lets this function set the opposite of the current value. So from the shell you could do a:
setx; echo "y" | ( cat -t ) | echo "d"; setx
and it will turn on debbuggin.
This is an amazingly useful function that is perfect to add system-wide by adding it to /etc/profile or /etc/bashrc.. You can run it from the shell, and you can also use it in your shell scripts like my .bash_profile - http://www.askapache.com/linux-unix/bash_profile-functions-advanced-shell.html
There is 1 alternative - vote for the best!
Turn shell tracing and verbosity (set -xv) on/off in any Bourne-type shell
If either -x or -v is set, the function turns them both off.
If neither is on, both are turned on.
