Add that line into your .profile file located at /etc/profile , the in the next login you will load that automatically.

Or just change your shell with usermod:

usermod -s /usr/bin/ksh

Well, just setting the SHELL variable does not mean you are actually using ksh now. It just means that the SHELL variable contains /usr/bin/ksh.

To actually use ksh in the current session you can do:

# /usr/bin/ksh
or
# exec /usr/bin/ksh

To always use ksh you can change your default shell in the /etc/passwd file. HOWEVER, NEVER EVER EVER CHANGE ROOT's DEFAULT SHELL. It must ALWAYS be /sbin/sh.

To change your default shell in /etc/passwd you can use the usermod command (see the usermod man page for details) or, if you have permission, you can edit /etc/passwd, preferably with vipw.

First on an HP-UX box there is no reason to run the Korn shell. /usr/bin/sh is not the Bourne shell but is rather the POSIX shell and the behavior of the POSIX is all but indistinguishable from that of the Korn shell. The POSIX shell is a superset of the Korn shell.

As for your Ctrl-C question, I am having trouble finding a question. You may want Ctrl-C to be the default interrupt key, if that is the case then insert a line 'stty intr "^C"' in the user's .profile.

The simplest way to change your shell is to use chsh -- no root capability required. Like this:

chsh billh /usr/bin/ksh

Your CTRL-C problem is caused by not logging in in a 'normal' manner (for example, using Xwindows), or someone has clobbered your .profile. All HP-UX come with a standard .profile that set CTRL-C (and several other important terminal settings). If someone has 'improved' your .profile by borrowing one from another flavor of Unix, just replace it with the standard version:

cp /usr/newconfig/etc/skel/.profile $HOME/.profile

If you are running Xwindows, then your terminal window is probably bypassing standard login scripts. Change to standard behavior by doing this one time for each user:

echo "*loginShell: true" >> $HOME/.Xdefaults
