bash
To only show the last 2 directories in prompt, there are two scripts at the Muffin Research Labs. 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 %~.
