How to produce a PS1 prompt in bash or ksh93 similar to tcsh
.everyoneloves__top-leaderboard:empty,.everyoneloves__mid-leaderboard:empty,.everyoneloves__bot-mid-leaderboard:empty{ margin-bottom:0;
}
In tcsh, I have the default:
prompt [%m:%c3] %n%#
which gives prompts like:
[woehler:hacking/c/hello] ajcarr%
and
[woehler:~] ajcarr%
In other words, the current directory and up to the next two above it in the path.
In ksh93 or bash, the substitution of $HOME by ~ is easy, as is extracting the name of just the current directory, but I have yet to find a way of replicating the %c3 behaviour of tcsh. At present in ksh93 I have:
[ajcarr@Woehler] hello $
and
[ajcarr@Woehler] ~ $
Does anyone have any suggestions about how to do this?

For bash, you could achieve similar results by setting the PROMPT_DIRTRIM variable:
$ PS1='[u@h] w$ '
[schaller@r2d2] ~$ pwd
/home/schaller
[schaller@r2d2] ~$ PROMPT_DIRTRIM=3
[schaller@r2d2] ~$ cd /home/schaller/tmp/513924/another/directory/here
[schaller@r2d2] ~/.../another/directory/here$

In ksh93:
PS1='${PWD#${PWD%?/*/*/*}?/} $ '
share/doc/libnl-3-dev $ _
PS1='[${HOSTNAME%%.*}:${PWD#${PWD%?/*/*/*}?/}] $USER% '
[host:share/doc/libnl-3-dev] user% _
If you want it to also replace $HOME with ~, something nastier[1] is needed:
PS1='$(d=${PWD/#$HOME/"~"};printf %s "${d#${d%?/*/*/*}?/}") $ '
~/w/maemo $ cd sb2-pathmaps
w/maemo/sb2-pathmaps $ _
This should also work in bash, though bash has its own prompt escapes (eg. h for ${HOSTNAME%%.*}) and path shortening mechanism (with PROMPT_DIRTRIM).
zsh has prompt escapes quite similar but not identical to tcsh:
zsh$ PS1='[%m:%3c] %n%# '
[host:share/doc/libnl-3-dev] user% _
[1] there may be some consolation in the fact that ksh93 doesn't fork() another process for subshells which contain only builtins, like that $( ...; printf ...) ;-)
