i'm writing a chapter on user and group management in linux,
and was just about to mention the "newgrp" command, when i read
both the man and info page and was totally confused.
reads the man page (in part):
... the current directory is unchanged, but calcula
tions of access permissions to files are performed with
respect to the new group ID.
this is (clearly?) incorrect. as i understand it, your group
access rights to any file are based on the *combination* of your
primary login group (as listed in /etc/passwd) and your additional
groups (as listed in /etc/group), all of which are listed when you
run either of:
$ id
$ groups
as i recall, the new group represents the group ID that will
be attached to *new* objects you create -- files or directories.
am i just misreading the man page, or has the functionality
of "newgrp" changed dramatically while i wasn't looking?
