customise prompt - sh, ksh, bash

[dbase77]

hi,

quick question about solaris shells. How do i customise unix shell for sh, ksh, bash? For example i want my prompt like "username@machinename path >" . the path will change every time i change my path.

thank you in advance.

regards,
feroz

This should work in ksh and bash. Put the following 2 lines in your .profile

PS1='$LOGNAME@'`uname -n`' $PWD >'
export PS1

In the bourne shell (sh) there is no environment variable that holds the current working directory. I don't think you can do what you want in bourne shell.

You could try this in the .profile :

_cd() {
cd $*
PS1="${PWD} >"
}
alias cd=_cd
cd .

or better, put this in .kshrc the add this to .profile :

ENV=${HOME}.kshrc ; export ENV

The difference is that .profile is executed when you log on, and .kshrc when you call a shell, so this way you don't lose the PS1 variable when you start a new shell.
hoope it helps.

I like that idea Mike, but unfortunately the alias command doesn't work in sh. Also, $PWD env variable is not maintained in bourne shell, so you would need a line in your function like:

PWD=`pwd`

Is there an equivalent to alias in the bourne shell?
