Equivalent bash shell prompt (linux) in POSIX shell prompt (HP-UX)

[yc_2]

Hi,

In linux, I can set the shell prompt as follows:
:
PS1=[\u@\h \W]\$
:

Is there an equivalent for \W in HP-UX POSIX shell ?

Where \W is an escape sequence of the basename of the current working directory.

Hi,

I did not try this with a sh-posix shell, but with a Linux Korn shell (na \\W available either).

Try:

export PS1='[${PWD}]\\$ '

So, use single quotes!

This should put the current working directory in the prompt.

Hope this helps,
Rik

Hi again,

In the previous version of the forums, a backslash had to be escaped.

That's why you see 2 backslashes in my previous post. It should be just one backslash, of course.


Bye,
Rik.

Hi,

This should do the trick !

export PS1="[ $PWD ] "

Good luck !

Hi,

I don't need a full path directory, I only need the last directory of the full path. This can be done in Linux Bash shell with \W.

Hi,

Ok this is the thing for the last dir !

export PS1=${PWD##*/}

Hi,

Try this one:

export PS1='[$(basename ${PWD})]\$ '

Mind that the single quotes are required. In the case of double quotes, the value is fix and will not change after a directory change.

Bye,
Rik

Hi,

all together there are a lot of options, but I think this is the final one you meant to achieve.

export PS1='[(${PWD##*/})]\$ '

This one will only display the last directory you are in and is changing again when you cd to an other directory.

Hi Clemens,

Would you like to share where can I learn these tricks ?


Thanks,

Hi,

Any decent shell programming book -- Korn, Bourne, or POSIX -- will have these "tricks". Another great place to learn shell programming is in HP's POSIX Shell Programming class. Five days of shell tips, tricks, and programs.

Here is what I have:

export VISUAL=emacs

MACHINENAME=`uname -n | cut -d. -f1`
export PS1='$MACHINENAME:$PWD> '

The first line is to use command line editing by pressing ctrl-p and ctrl-n for previous and next command typed. Cursor movement is down by ctrl-f and ctrl-b. I like this one over seting it to vi.

The last 2 lines give you a prompt like

castor:/home/felix>

The path on the prompt will get longer and longer as you go deep into subdirectories.

P.S. There is a ksh in linux distribution, named pdksh.

You might want to install the bash shell on your HP-UX system. It's usually the first thing I install on an HP box after HP-UX. You can find a software distributor (SD-UX) package at:
http://hpux.cs.utah.edu
or you can download and compile it if you like from a number of places.
