Just for future advise.. for someone who says they don't want to start a flamewar.. you worded that pretty much like you wanted to start a flame war. This was simple to test. 1. I installed RHEL-7 in a virtual machine. 2. I created an account with its shell /bin/tcsh [useradd ssmoogen -s /bin/tcsh ] 3. I went to the login screen. There was an ssmoogen there 4. I logged in as ssmoogen. I got a GNOME desktop 5. I opened a terminal and my shell was tcsh. That took me 10 minutes. Due to this I am going to say that there is something wrong with other parts of the start up environment from what the shell is listed as in /etc/passwd, if the user has specific startup scripts .xsession items or some similar problem based on 'shell cruft'. People who work on many different systems have to regularly add exceptions and special cases or unadd them when they find stuff breaks. I would also check to see if there is a post configuration setup which changed /etc/shells on the system. Another common problem is that the shell or startsups are looking for /usr/local/bin/tcsh which doesn't exist. Red Hat has a lot of different developers using pretty much every shell that is shipped in RHEL and some which aren't even in Fedora. The developers also use all kinds of different desktops and software.. while this doesn't mean bugs won't happen.. it does mean that if 'Red Hat' was out to eradicate other shells, there would be posts on every hacker site from Red Hat employees who wouldn't put up with it. > Thanks in advance for all your answers. > > Valeri > > ++++++++++++++++++++++++++++++++++++++++ > Valeri Galtsev > Sr System Administrator > Department of Astronomy and Astrophysics > Kavli Institute for Cosmological Physics > University of Chicago > Phone: 773-702-4247 > ++++++++++++++++++++++++++++++++++++++++ > _______________________________________________ > CentOS mailing list > CentOS@centos.org > https://lists.centos.org/mailman/listinfo/centos -- Stephen J Smoogen. _______________________________________________ CentOS mailing list CentOS@centos.org https://lists.centos.org/mailman/listinfo/centos
