@ liming xing
Read ‘man bash’. It is explained into the FILES section, at the end.
It is ~/.bash_profile or ~/.bashrc.

Hello:
Excuse me, how do I get in shell file PS1 variables

It’d be nice to note in (9) that export PS1=”\u@\h [`httpdcount`]> ” would render the httpdcount *when the window is opened* while export PS1=”\u@\h [\`httpdcount\`]> ” would render an updated httpdcount each time a prompt is rendered.

I’m using
export PS1=”\h:\`pwd | sed ‘s/^.*$\/.*\/.*$$/\1/’\`$ ” to display the most recent 2 directories.

For years now I’ve been using something like
PS1=”\`if [ \$? != 0 ]; then echo \[\e[33m\]—=== \[\e[31m\]Oh noes, bad command \[\e[33m\]===—; else echo \e[33m\]#Yay, comamnd succeeded\[\e[0m\]; fi\`\n\n\[\e[0;37m\]#\[\e[1;34m\]xX \[\e[1;32m\]Company Inc. \[\e[1;34m\]Xx\n\[\e[0;37m\]#[\[\e[1;34m\]\w\[\e[0;37m\]]\[\e[0;37m\][\[\e[1;31m\]\j\[\e[0;37m\]][\[\e[1;35m\]\A\[\e[0;37m\]]\[\e[0;37m\][\[\e[0;32m\]\!\[\e[0;37m\]]\[\e[0;37m\][\[\e[1;32m\]\#\[\e[0;37m\]]\n\[\e[0;37m\]#\[\e[0;32m\]\u@\H \[\e[1;31m\]\$ \n ”

Which gives me something like:

#xX Company Inc. Xx
#[~][0][23:58][507][6]
#User@Host $

The top is a vanity header, the bottom is pretty much your standard User@Host.All commands start at the next line, which when paired with the leading hashes, helps make for easy script copying, as mentioned before. The second line is really where I get all the info I need. It breaks down as:

#[Working directly][Number of jobs in background][Time in 24H format][History of command][History of command for this session]

Also, if the command succeeds, I get a “#Yay, comamnd succeeded” – if it fails, I get the “—=== Oh noes, bad command ===—” message.

Sorry for the multiple posts, but I now realize that the only thing needed to accomplish this is to include a backslash before the $PWD. This ensures that the current working directory is determined each time the prompt is created; without the backslash it would be determined just once and would never change.

PS1=”\u@\h \$PWD>”

On reflection, it looks as though something as simple as this works:

PS1=”\u@\h \$(echo -n \$PWD)>”

I’m liking the examples! Here’s a possible way to get the prompt to list the home directory in the “/home/username” format instead of a tilde (~):

curdir(){
if [ $PWD == /home/$USER ]
then
echo -n /home/$USER
else
echo -n $PWD
fi
}

PS1=”\u@\h \$(curdir)>”

Hello,
I have a strange error when I try to set PS1. I use
PS1=”\h:\w $ ”
because I want the host followed by the current working directory. But the prompt I get is:
h:w$

How do I correct this?

Just for fun, I wanted to emulate the MS-DOS prompt:

function msdos_pwd {
echo `pwd` | tr ‘/’ ‘\\’
}

export PS1=’C:`msdos_pwd`> ‘
