[Bug 1319676] Re: sudo launched root prompt not the program

Thu May 15 17:34:32 UTC 2014

Thanks for filing a bug report; however, your log looks exactly as
expected.

The 'admin' user should not be confused with the system's superuser
account 'root'. 'admin' is something that is local to your site and
unless you or your system administrator has gone to some effort to
configure local filesystem permissions and perhaps group permissions,
the user 'admin' wouldn't be expected to be able to write into a
directory owned by the user 'b21an'.

Note especially that 'script' presents you with a new shell and records
all input and output from that shell, and commands you type there. It is
expected that it gives you a new shell prompt, and when you used 'sudo'
to start script, it gave you the expected # prompt. If you didn't want
to run 'script' as root, you should leave off the 'sudo'. You could use
the command line parameter to specify a place that the 'admin' user has
write privileges too, such as the admin user's home directory, like
this:

$ script ~admin/typescript

When you want to exit the shell started by 'script', type 'exit' or use
the usual ^D.

Thanks
