[Help-bash] Editing a running bash script can cause it fail?

[Peng Yu]

Hi,

It seems that a bash script is not first load into memory completely
and then get run. Is it the case? I think that this is true because
modifying a running bash script sometimes causes the existing run of
the script fail.

If so, is there a way to let bash read a script completely before
running it so that editing the script will not cause the run fail?
Thanks.
