Well, this requires a zero-length perl program.
Zsh supports this feature directly, and it's part of my standard setup,
which is, on xterms:
prompt='%{ESC];%n@%m %~^GESC]1;%m %.^G%}%2. %# '
This writes the full directory name (with '~' contraction) into the
window title, and abbreviated ones into the command line and icon box (2
and 1 components respectively). Do I have to say that you replace ESC
and ^G with the control characters?
Sorry, no perl and not much fun. Just a sales pitch for zsh. Zsh has
been described as having every feature you could possibly want in a
shell, except for small size. It's still smaller than bash, though :-)
