Top Forums UNIX for Dummies Questions & Answers problems with ctrl-z, to switch foreground, background Post 35405 by Perderabo on Thursday 10th of April 2003 10:43:01 PM

That would be dangerous. root should have a staticly linked shell so that it can run when the shared libraries are not available. And /usr is often a separate file system. /usr/bin/ksh will not even be present until /usr is mounted.

Also, vipw will demand that root's shell be the default or it will fail.

After you "su" to root, just type:
exec ksh
or
exec bash
or whatever to get a real shell.

And remember, don't stay in root for very long. Get in, do what you must, and then get out. Run as an ordinary user whenever that is possible.

vipw

vipw(1B)					     SunOS/BSD Compatibility Package Commands						  vipw(1B)

NAME

       vipw - edit the password file

SYNOPSIS

       /usr/ucb/vipw

DESCRIPTION

       vipw edits the password file while setting the appropriate locks, and does any necessary processing after the password file is unlocked. If
       the password file is already being edited, then you will be told to try again later.  The vi(1) editor will be used unless the  environment
       variable VISUAL or EDITOR indicates an alternate editor.

       vipw performs a number of consistency checks on the password entry for root, and will not allow a password file with a "mangled" root entry
       to be installed.  It also checks the /etc/shells file to verify the login shell for root.

FILES

       /etc/ptmp

       /etc/shells
