Maybe I should elaborate.

I'm currently working on a small script that typically runs for about 8 
minutes. Part of what it does is set up a RAID array on a 3WARE 
controller and then partition that space using fdisk and then format 
that partition for an ext3 file system. All this takes time on a 2TB array.

While the script is executing, if I see something I want to fix or add 
to the script, can I emacs the script file and modify it while it is 
still being executed?

I use debug code and lots of functions already, and I have some scripts 
that are over 4000 lines long.

When a script exits abnormally, I'm looking for a convenient way to 
quickly modify the script to immediately "goto" where the last execution 
left off and continue on.
i.e. while setting up the drive array as previously described, if the 
fdisk fails for whatever reason, and the script terminates, I want to 
make a fix to the script to bypass the parts that already ran 
successfully and retry the fdisk and continue on down thru the end of 
the script.
