I am unable to launch MCC as "user" Clicking on MCC icon and mgaaplet nothing happens
I would be curious to know where $SHELL is initially defined and how it
is corrupted
I tried defining in /etc/environment
and tried to declare in the bash CL but it isn't permanent.
Finally put it in ~/.bashrc where it works.

Have you tried a test account, say junk, to see if it is a system
wide problem or user problem?

A place to start looking
grep -ir shell /etc/profile.d/*.sh
That would require a bit of work on your part. I had to modify the
INVOCATION files to dump desired info for debugging these kinds of
problems.

Shuckey dern, you are correct. Back to speed reading 101 for me.
As for an owner check the command would be
find $HOME \( -not -user $USER -or -not -group $USER \) -exec ls -ald '{}' \;
But that is not going to corrupt the bash env variable.
But I''l try it again later this afternoon
SO... which was original and was changed to reflect `SHELL=/bin/bin` and
then broke "drakconfig" and trashed my quiet afternoon.

What does "grep $USER /etc/passwd" show? The 7th (last) variable defines
the
shell to use, and does set the initial value used for $SHELL in the environment
when the user logs in, though it may be altered by scripts later in the login

That's the best clue so far for the origin
But my passwd login shell was is /bin/bash. Surely no program would
change that - I hope
Problem has got to be in your account.
Back out your .bashrc change, boot run level 3, log in and
echo $SHELL
if valid you know something in Desktop Environment is causing the
problem.

Yes! and it has cleared up
Back out your .bashrc change, boot run level 3, log in and

it was /bin/bash
and it still is, on the Desktop with the .bashrc shell entry remmed out
FWIW Since the shell mod and the user passwd editing yesterday I
have a new user on the login screen called "system user for..."
It's not in the passwd file
if valid you know something in Desktop Environment is causing the
problem.
I have been going over the events of yesterday as much as I remember and
I am staring to blame myself.
When I edited the passwd file experimentally to show /bin/nologin, did I restore it properly afterward?.
Could I have typed /bin/bin?
Have I given myself the runaround?
It seem more likely than an OS fault. PEBKAC
I suppose the upside of dumb-ass errors is the education you get from them.
You might want to run

grpck -r

Did you copy one or more of the files /etc/passwd, /etc/shadow, /etc/group, and /etc/gshadow from another install or manually edit them?
The files are supposed to be kept in sync with each other and the standard utilities for working with them ensure that's done.
I think it's saying that according to /etc/group your id is in the lp
group,
but isn't in the lp group according to /etc/gshadow. Same with the other groups it's showing.
I have no idea what type of impact that may have.
First check the permissions ...
# ll /etc/passwd /etc/shadow /etc/group /etc/gshadow
-rw-r--r-- 1 root root 2581 Jan 1 17:48 /etc/group
-r--r----- 1 root shadow 2188 Jan 1 17:48 /etc/gshadow
-rw-r--r-- 1 root root 5652 Feb 7 17:04 /etc/passwd
-r--r----- 1 root shadow 2444 Feb 7 17:04 /etc/shadow
Read "man pwconv". After fixing the permissions and ownership if needed,
I think
running the "grpconv" command will repair the gshadow file.

The rest do nor really matter unless you want something to actually
login to those users.
(They also exist on my Mga8-- some problem in the installation rpm
scripts I presume).
Since you undoubtedly do not have any passwords anyway, it does not
matter. However, if you did have group passwords, this would allow you
to user your group identity without a password (man gshadow)

The usermod program doesn't like the space after the comma, so the
command failed
with no changes made.
While creating the directories shouldn't cause any harm, it also doesn't do anything useful. It is just a waste of resources and a potential cause
for a
future bug if the ownership/permissions are not set as they would be by those
packages.

Not hardly. If you were to grep /etc/passwd for each, you can
get the uid:gid. For example
# grep uucp /etc/passwd
uucp:x:10:14:uucp:/var/spool/uucp:/bin/sh
mkdir -p /var/spool/uucp
chown 10:14 var/spool/uucp

I screwed up, there should not have been any spaces in the group list.
Also forgot to add your user id. Updated the faeychild text file to have

But should it be root owned with the group set to uucp, vice-versa, or both set to uucp? Should it be only owner readable, etc.?
Set the permissions wrong and then install a usenet feed sharing program (i.e. one
of the uucp server packages), and it may or may not work properly with the settings
chosen, if that program doesn't alter the choices for an existing directory and
only sets them if it creates the directory on the package installation.
Other then getting rid if the messages from the grpck/pwck programs which you normally should not be running manually, creating the directories is of no use
and may cause problems later.

A trailing ' \' on a bash command tells bash that there are more

Then you might not have access to files/directories that you want.
The question is somewhat vague, to me, based on your latest adventure.No idea what you mean. Do you have an example?
For instance you have decided to quit mucking around with with a file
editor in passwd/group and chose to use mcc. It is pretty easy for you
to just check box the desired groups, but it is just as easy to change
your primary group which will prevent you from logging in and/or access
to other files.
I suggest that any future experiments be done to a test account. :)

You do not have to be, assuming that that group is what is listed in /etc/passwd/
username:password:uid:gid:Name:homedirectory
That gid is automatically associated with that userid. No need to make
it explicit in /etc/group. And it could be any gid, it does not have
to have the username as the groupname.
Eg, youo could have all users have the same gid, making it easier for
them to share files.

something. If a user changes their primary group ( which the
installation script in Mageia makes their own group) I cannot imagine
how that that could cause trouble in booting or in logging in. AFAIK,
the files in the user's home have both the UID and the group be the
user's UID and primary group. Or sometimes perhaps, the user's UID
and the group of some other system service (although I have not seen
any file like that . I just checked and all files in my home have
group be my primary group).
=20
But even if I changed them all, I would not expect to have any
problems booting. Again I may have overlooked something which is why
I am asking.
Whether the user has read or read/write access to directories andst
files has nothing to do with what the user's primary group is,
although it may depend on whether the user belongs to the group that
owns the directory or the file =E2=80=94 emphasis on "may", because in mo=
GNU/Linux distributions intended for desktop use, just about every system-owned directory (except for /root [*]) has 755 permissions and
