I want to change ownership, group membership and access rights in a script by a sequence of commands.
Some of them need root permissions.
I first did sudo su in a terminal and then ran all the necessary commands once in a row. I found out that after sudo su all macro definitions abc=<...> have to be put after sudo su, because it seems that root does not know about macros existing in the other context.
After all my commands worked as expected, I called histoy, removed the line numbers and framed the relevant part of it in sudo su ... exit.
I can paste this sequence of commands into a terminal and it runs fine.
However if I prepend it with a line #!/bin/bash and store it as a file and make that executable, that does not work:
I get prompted for the password, but then I end up at a command line level, with the prompt ending in #, which shows me that sudo su has worked. But the rest of my command sequence has not worked.
How can I achieve the other commands to be executed?
Being a command line newbie, I guess I haven't understood something important yet. Please explain how to do it and why.
