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$
add a comment |
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 $HOME
with ~
, something nastier is needed:
PS1='$(d=$PWD/#$HOME/"~";printf %s "$d#$d%?/*/*/*?/") $ '
~/w/maemo $ cd sb2-pathmaps
w/maemo/sb2-pathmaps $ _
PS1='$(d=$PWD/#$HOME/"~";printf %s "[$HOSTNAME%%.*:$d#$d%?/*/*/*?/]") $USER% '
[host:w/maemo/sb2-pathmaps] user% _
All this should also work in bash
, though bash
has its own prompt escapes (eg. h
for $HOSTNAME%%.*
) and path shortening mechanism (with PROMPT_DIRTRIM
).
Also, the nastier variant will be really nasty, because bash
, unlike ksh93
, will fork()
a separate process for each $(...; printf ...)
command substitution, even if it contains only builtins. This also holds true for pdksh
derived shells, like mksh
.
zsh
has prompt escapes quite similar but not identical to tcsh
:
zsh$ PS1='[%m:%3c] %n%# '
