login shell

Oliver Schmitz — Wed, 08 Oct 2003 08:26:53 GMT

Dear all,

how can I define the default startup shell of a user. I saw that it is possible when I create a new user with sam. How can I do it afterwards?

Can I define every shell installed?

Thanks ,

Oliver

Hi Oliver,

The default shell is defined in the last (7th) field of the users entry in the /etc/passwd file.
You can use vipw to safely edit the passwd file or use SAM to modify the user.

HTH,
Jeff

Oliver,

As you've noted, you can do it in SAM when adding the user. You can also do so with "useradd -s" when adding the user. To change the shell afterward, the easiest way would be to use vi (or perhaps sed) on the /etc/passwd file.

Oliver

it is defined by the last field in /etc/passwd. You can use any shell.
You can use any shell, can also use a script that is run upon login...

Bernhard

Oliver,

One other thought: If you're going to be changing shells, make sure the shell you've chosen is listed in /etc/shells. If you don't have /etc/shells, create it and add the shell to it. Here is a basic /etc/shells:

$ more /etc/shells
/bin/sh
/bin/rsh
/bin/ksh
/bin/rksh
/bin/csh
/bin/pam
/usr/bin/keysh
/bin/posix/sh
/sbin/sh
/usr/bin/sh
/usr/bin/rsh
/usr/bin/ksh
/usr/bin/rksh
/usr/bin/csh
/usr/bin/keys

Oliver,
The 7 column corresponds to the shell which is invoked when the login successfully completes authentication.
/usr/bin/sh is the default shell. You can choose also /usr/bin/ksh.

When adding users through SAM you can see this option.

If you want to change that for a particular user
usermod -s

Umapathy

One thing to note if you do change users' shells --- *DO NOT EVER* change the default shell for root. It *MUST* be /sbin/sh. If it is anything else you rish an unbootable server.
