bash
====
To only show the last 2 directories in prompt, there are two scripts at the [Muffin Research Labs](http://muffinresearch.co.uk/archives/2007/09/25/showing-last-two-directories-of-pwd-in-bash-prompt/).
The best one would be this:
{% highlight bash %}
function PWD {
tmp=${PWD%/*/*};
[ ${#tmp} -gt 0 -a "$tmp" != "$PWD" ] && echo \<${PWD:${#tmp}+1} || echo $PWD;
}
{% endhighlight %}
Add this to `.bash_profile` and replace `\w` by `$(PWD)` (note the parents!) in your `PS1` line in that file.
A more comfort version which replaces the home directory by a tilde, is the following. I changed the function name to
`PWD2` to highlight the difference to the normal `PWD` variable.
{% highlight bash %}
function PWD2 {
xpwd=${PWD/$HOME/"~"};
tmp=${xpwd%/*/*};
[ ${#tmp} -gt 0 -a "$tmp" != "$xpwd" ] && echo «${xpwd:${#tmp}+1} || echo $xpwd;
}
{% endhighlight %}
zsh
===
The zsh has this feature built-in. Use this to show only 2 parts of the PWD:
%3(~.«.)%2~
This says: If `%~` (the prompt incl. replacements such as `~` for homedir) has 3 or more parts, show `«`.
After that show 2 parts of `%~`.
