[Solved] script question - theory

[lightman47]

Way back in my Windows days, I found out that editing a running network based batch file 'raised the dickens' with the machine running it. Apparent was that Windows read, then executed, a line at a time.

Is the same true of linux (CentOS) scripts? Or, are they read into memory in their entirety and executed from there? I ask because I have a machine currently running a shared backup script which has 'spit out' an error to it's log file, and I want to edit the scripts to fix my screw-up before I forget about it yet again. Can I safely edit the script while a machine is running it, or must I wait till it's done?

Thank you

Move the old script to a new name. As long as the process has the file open, it will continue reading that file regardless of the name change.
Then create a new copy of the file with the original name and make your edits. That file will then be used the next time.
