File name/Line numbers with tracing output.

[Edward Peschko]

All,

I've been working lately at upgrading my debugging tools and procedures, and 
have come to looking how I can improve debugging bash.

I know about bash -x , but its terribly annoying because, even though it shows 
the evaluated text, there is no explicit way to tie that output back to the 
script that ran it. For example, with a script like:

echo $x

Where x = 1, when you run bash -x , you will see:

+ echo 1

With no obvious way to tie this back to the place in the script that ran bash.


What I was wondering is if there was a way to make this explicit, ie: bash -X 
(or somesuch) which would output something like:

ltmain.sh:110 + echo 1

Where ltmain.sh is the name of the script, and line 110 is the line # of the 
associated program.

So - does something like this exist, and if not, would it be easy to add?

Thanks,

Ed
