Miscellaneous: Zsh: prompts(last edit: 2001-03-18)
You can alter your zsh 'PS1', 'PS2', 'PS3' and 'PS4' prompts via the command line or your
'~/.zshrc' file by resetting the value of the matching shell variable. This is e.g. '$PS1'
for the 'PS1' prompt.
user@host:~#export PS1="%m [%n] %d>"
Would generate a default prompt like this:
lowlife [jappe] /home/jappe>
This is how my '.zshrc' looks like:
export PS1="%m [%n] %d>"
You can type the same command on the command line instead of putting it in your '~/.zshrc'.
Here are some options and explanations extracted from the 'zshparam' man page:
PS1 The primary prompt string, printed before a command is read; the default is "%m%# ".
%/ Present working directory ($PWD).
%M The full machine hostname.
%m The hostname up to the first '.'.
An integer may follow the '%' to
specify how many components of the
hostname are desired.
%@ Current time of day, in 12-hour,
%T Current time of day, in 24-hour for-
%* Current time of day in 24-hour for-
mat, with seconds.
%w The date in day-dd format.
%W The date in mm/dd/yy format.
%D The date in yy-mm-dd format.
PS2 The secondary prompt, printed when the shell needs more information to complete
a command. Recognizes the same escape sequences as $PS1. The default is "%_> ",
which displays any shell constructs or quotation marks which are currently
PS3 Selection prompt used within a select loop. Recognizes the same escape sequences
as $PS1. The default is "?# ".
PS4 The execution trace prompt. Default is "+".
