Using csh, if I use the following scripts,

Quote:>   alias    cd 'chdir \!* && set prompt="$USER${cwd}# "'
>   if ($?prompt) then
>       set prompt="$USER${cwd}# "
>       set filec
>   endif

Can someone tell me how to do the same thing with Korn shell?

Thanks!

Something like

Should do the job.

When I posted the following message, everyone who has responded to me,
seems to be a bit confused. What the following script (embedded in
.cshrc) will do in csh is that whenever you change directory using cd
command, it will display the login user name and the changed directory.
For example, if you are a root and in /bin, you will get a prompt of
"root/bin# '. If you change directory to /usr/src by 'cd /usr/src'
command, your next prompt will become "root/usr/src# '. It's useful
because you always know who you are and where you are.

I only have O's csh manual and am waiting for the O's ksh manual. I need
to reprogram pdksh so that I can add some diagnostics command (It's
critical that this new command will not cause any filesystem access.). I
suppose that the same capability with ksh might be a bit more difficult
because ksh doesn't seem to have an embedded 'chdir' command.

Anyhow, I still appreciate helps from everyone and am still looking
forward to getting a right answer. Hope someone has already done this!

p.s. Since this will happen for every cd, I'd like to see the solution
primarily based on the internal commandsof ksh. I still appreciate all
the helps!

Umm, if you really want it to look that way, how about putting the

PS1='${PWD}# '

You do not need to execute something every time you change directory.
Try it. :-)

but there are a number of factors involved:

        1) other code (trimmed out) also changes the TITLEBAR of the
           window.

        2) people who use /bin/sh as their login shell get the exact
           same functionality (except they have to use 'go' in place of 'cd')

since i'm working in a mixed sh and ksh environment, i found this works
for me...

YMMV

PS1='$LOGNAME$PWD# '

will achieve exactly the effect you describe in ksh: PWD is automatically
updated and the variables are re-evaluated every time the prompt is
displayed.  (Make sure you use single quotes or it won't work.)
Did you try it?  Why isn't it adequate for your needs?

mycd()
{
  cd $*

Quote:}

If you want something to be done whenever the prompt is redisplayed,
whether or not cd was used, use trap DEBUG, possibly again with a function
(as has also been suggested):

trap my_prompter_function DEBUG

If your problem is avoiding file system access, these shouldn't
cause any unless your functions do, besides possibly updating the
history file: that can be avoided by unsetting the HISTFILE variable.

If still can't make it work the way you want, please explain exactly
what you tried, what happened and what you would've wanted to happen.

I found this some time ago at this same ng:

JOSTNAME=`tput bold``hostname -s``tput sgr0`
TILDE='~'

'

sorry but I don't remember the name of the original
poster

Another way

EMOH=`echo $HOME | sed -e 's/\//\\\\\//g'`

_cd()
{
    if [ $# != 0 ]
    then \cd $*
    else \cd
    fi

    export PS1=${JOSTNAME}':'`pwd | sed -e "s/${EMOH}/~/"`'> '
