Description John V. Kjellman 2002-07-11 19:39:10 EDT

Description of problem:
'newgrp' not listed in your bug list! I know problem is not with 'release' 
file.  The problem with 'newgrp' is that when executed it causes functions 
defined in /etc/bashrc and .bash/profile files to become undefined. The man 
page does not describe this as a feature, so I assume it is a bug. It is 
annoying!  The execution of 'newgrp' should only change a user's group ID, 
nothing more.  Thank you.

Version-Release number of selected component (if applicable):

How reproducible:

Steps to Reproduce:
1. create a simple function in /etc/profile if there is not one already defined
2. logon as user with permission to be in two or more groups
3. test use of function
4. newgrp {alt-group from login group}
5. test use of function [it will fail]

Actual Results:  The function no longer works

Expected Results:  I would think that all functions defined previous to 
execution of 'newgrp' would continue to be defined after assigned to the new 

Additional info:

This applies to RH 6.2 and RH 7.2. The man page does not mention this behavior 
as being a feature of the program.

It's part of the util-linux package. I'm changing the component and assigning to
the owner of that package.

newgrp does not change the group of the current shell, but runs a new shell with the new 
group, as a subprocess of the current shell. This new shell is not a login shell and won't 
behave the same way.
Comment 3 John V. Kjellman 2002-08-13 09:11:49 EDT
May I respectfully suggest that the man page be updated to reflect this 
information.  The current man page refers to "login." Thanks.  John Kjellman
