When you add a new user, the default shell is taken from /etc/adduser.conf.
On a new box, this file doesn't exist until you run adduser once.
So I ran adduser. Note that I could have specified a different bash shell.
See the bold line below. Instead, I chose to modify /etc/adduser.conf
manually. See below for those steps.
# adduser
/etc/adduser.conf: No such file or directory
Use option ``-silent'' if you don't want to see all warnings and
questions.
Check /etc/shells
Check /etc/master.passwd
Check /etc/group
Enter your default shell: bash csh date no sh tcsh [sh]:
Your default shell is: sh -> /bin/sh
Enter your default HOME partition: [/home]:
Copy dotfiles from: /usr/share/skel no [/usr/share/skel]:
Send message from file: /etc/adduser.message no
[/etc/adduser.message]:
Create ``/etc/adduser.message''? (y/n) [y]:
Use passwords (y/n) [y]:
Write your configuration to /etc/adduser.conf? (y/n) [y]:
Ok, let's go.
Don't worry about mistakes. I will give you the chance later to
correct any input.
Enter username [a-z0-9_-]: deleteme
Enter full name []: deleteme
Enter shell bash csh date no sh tcsh [sh]:
Enter home directory (full path) [/home/deleteme]:
Uid [1002]:
Enter login class: default []:
Login group deleteme [deleteme]:
Login group is ``deleteme''. Invite deleteme into other groups:
guest no
[no]:
Enter password []:
Use an empty password? (y/n) [y]:
Name: deleteme
Password: ****
Fullname: deleteme
Uid: 1002
Gid: 1002 (deleteme)
Class:
Groups: deleteme
HOME: /home/deleteme
Shell: /bin/sh
OK? (y/n) [y]:
Added user ``deleteme''
Send message to ``deleteme'' and: no root second_mail_address
[no]:
deleteme,
your account ``deleteme'' was created.
Have fun!
See also chpass(1), finger(1), passwd(1)
Add anything to default message (y/n) [n]:
Send message (y/n) [y]:
Copy files from /usr/share/skel to /home/deleteme
Add another user? (y/n) [y]: n
Goodbye!
Then I changed the default shell entry in /etc/adduser.conf:
# defaultshell if not empty ("bash")
defaultshell = "bash"
The next time you run adduser, you'll find this:
# adduser deleteme2
Use option ``-silent'' if you don't want to see all warnings and
questions.
Check /etc/shells
Check /etc/master.passwd
Check /etc/group
Enter your default shell: bash csh date no sh tcsh [bash]: ^C
[root@set:~] #
See? The default shell is now bash.
Then I went back to delete the user I added above:
[root@set:~] # rmuser deleteme
Matching password entry:
deleteme::1002:1002::0:0:deleteme:/home/deleteme:/bin/sh
Is this the entry you wish to remove? yes
Remove user's home directory (/home/deleteme)? yes
Updating password file, updating databases, done.
Updating group file: (removing group deleteme -- personal group is
empty) done.
Removing user's home directory (/home/deleteme): done.
Removing user's incoming mail file /var/mail/deleteme: done.
Removing files belonging to deleteme from /tmp: done.
Removing files belonging to deleteme from /var/tmp: done.
Removing files belonging to deleteme from /var/tmp/vi.recover: done.
