tracing inside functions
Using bash 2.05, does anyone know of a way to get a trace of what's
happening inside a function?
eg file /root/myscript:
#!/bin/bash
function x
{
LIST=`ls /someplace`
[ "$LIST" == "" ] && exit 0
mv $LIST /tmp
}
x
and then:
bash -x /root/myscript
will only show:
x
I'd like to see inside the function.
Bash 3 looks like it has extra debug stuff under shopt... but not
2.05.
Any clues?

I was able to run configure without errors using bash-3.2.17. I encourage
you to apply the available bash-3.2 patches and try it again.
