B.11 On-line editing

You can edit files on-line in two ways:

1. Using the shell access via ’!vi’
2. Using the ed function; this will edit the file but upon closing, it will try to execute the file; using the ’script.py’ example above:
     CASA [13]: ed script.py # this will bring up the file in your chosen editor  
                             # when you are finished editing the file,  
                             # it will automatically  
                             # execute it (as though you had done a  
                             # execfile ’script.py’  
       Editing... done. Executing edited code...
