You'd think , huh?
But it ($0 in the sourced shell) is not what what it's in the 'called' (not sourced) script - as the 'sourced' script runs in the same process space (there's no newly forked process) as the 'sourcing' script. Therefore, the '$0' in the sourced script is the '$0' of the sourcing script.
I'm not sure if I'm explaining this correctly - you can take a look at this
thread or browse this
comp.unix.shell user group for similar threads.
