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?
