You can also change the shell yourself.
You don't need the root password or a sys. admin Smile!

The below command assumes that ksh is installed in /bin/ksh.
If the ksh package is not installed you'll need root privileges to install
Or use sudo/sudoers if available.
Execute the following command to change your login shell:

$ chsh -s /bin/ksh

If you like ksh, a system administrator when they set up your account
can have your account come up in ksh for you.  Linux has several
different shells available to the user, Linux isn't Windows.  Even if
your account is set up with a different shell at first, you ought to be
able to get your sysadmin to fix that for you.

I find myself in somewhat the same boat just recently. I have just been
informed that we are switching all our HP/UX environments over to Suse
linux. While I have been asured that I can continue to use Tera Term for
my SSH sessions, I know there are going to be some differences between
the KSH shell I am used to and whatever shell linux is using. So, I will
be jumping into some linux book or books myself shortly. 
We use Weblogic instead of Apache but still I need to learn how to
manage the Weblogic environment under linuyx right away. So, while I
don't as yet have any suggestions, I will certainly be following this
thread closely.

        On the system I'm using, I don't have the authority to
administrate the operating system, but I do have the authority, and need
to, administrate the other software on the box that doesn't come with
it, so I need to come up to speed yesterday. You know how that is. 


        I cracked open the book called Learning The Unix Operating
System Fifth Edition and started using it to learn basic commands. Among
other things, two things are tripping me up. First, I'm using Putty. I
have it set up properly with JAWS, but I'm being driven crazy any time
data needs to scroll the screen because the whole screen is being


        The second thing has to do with knowing what I need to learn.
I'm just trying to learn what I need to know for now, and branching out
from there. Unfortunately, I'm not sure exactly what all that entales.
But fortunately, I do have some time, because we're just starting to use
MySQL and PHP. 


        So I see three big tasks or things to learn. 


        * What's involved in administrating Apache, like not letting the
logs get too big, possibly installing a friendly statistics package, or

        * Setting up daily backups of the changed MySQL database or
databases that we have.

        * Whatever MySQL administration that I have no earthly idea I
may need to do.

        * I'll have to upgrade MySQL at some point.

        * I'll have to upgrade PHP at some point.

        * I pray that I never have to upgrade Apache.

        * Possibly installing some nice, convenient packages like
PHPMyAdmin. But I'm thinking that like the people who were advocating
learning the dirty way, I think it's best to probably learn how to do it
from command lines so that I have total control and really know what's
going on.


        But I'm starting with basic commands, but at the same time,
trying to do my first Drupal installation, and I'm in real trouble
because of course there's this deadline. 


        Back to my UNIX book.


        Specifically, I didn't see in the book two things. First, what
permissions do files and directories automatically get when you create
them? Second, I used to know a little more about some sort of file in my
home directory that I could put stuff in to customize the environment a
little more. I know that that file has a name that starts with a period.
Yet another thing. I'm pretty sure that the shell I'm using is called
the bash shell, but I don't know how to find out. And how does that
affect how I work with the system? For example, if there's another shell
that's better, what is it, what does better mean, and how to I turn it


        Like I was thinking of making aliases for cp and rm that
automatically run the -i option to keep myself from trashing stuff. 


        Someone please hold my hand and tell me it'll be all right.
