BASH

[Bill Gradwohl]

Two questions:

1) When a BASH script is executed, the file that represents the script 
must be read by the interpreter. Assuming the script is a long running 
script, is it safe to modify the script while its executing? The real 
question boils down to is the entire script read into memory or not 
before execution starts, or is it read as needed from disk. I ask 
because I'd like to test a script, and while its running and I see 
errors, I'd like to modify the script without disturbing the executing 
version.

2) There seems to be no way to "goto" in BASH. If one has a lengthy 
script that fails half way down, the only thing to do appears to be to 
wrap the top half in an if that won't execute so as to skip that top 
half and get to where the script should again restart. Is there a better 
way to do this?
