I use this function die in scripts, like this:

    die() { echo >&2 "$*"; exit 100; }
    ...
    cp from to || die Error

I wanted to print, in the die, the line number of calling line. Is
this possible ?
I have script name in $), do I have access to the stack of callers
line numbers ?
Is it possible to print stack of line numbers and function names
of all finctions in the function call stack ?

Thanks
VM
