Formatting for the Prompt Variable

tcsh provides a list of substitutions that can be used in formatting the prompt. The list of available substitutions includes:

%%	Literal %.
%/	The present working directory.
%~	The present working directory, in ~ notation.
%#	# for the superuser, > for others.
%?	Previous command’s exit status.
%$ var	The value of the shell or environment variable var.
%{ string %}	Include string as a literal escape sequence to change terminal attributes (but should not move the cursor location); cannot be the last sequence in the prompt.
\c, ^c	Parse c as in the bindkey built-in command.
%b	End boldfacing.
%B	Begin boldfacing.
%c[[0]n], %.[[0]n]	The last n (default 1) components of the present working directory; if a leading 0 is specified, replace removed components with /<skipped>.
%C	Similar to %c, but use full pathnames instead of ~ notation.
%d	Day of the week (e.g., Mon, Tue).
%D	Day of month (e.g., 09, 10).
%h, %!, !	Number of current history event.
%j	The number of jobs.
%l	Current tty.
%L	Clear from the end of the prompt to the end of the display or the line.
%m	First component of hostname.
%M	Fully qualified hostname.
%n	Username.
%p	Current time, with seconds (12-hour mode).
%P	Current time, with seconds (24-hour format).
%R	In prompt2, the parser status; in prompt3, the corrected string; and in history, the history string.
%s	End standout mode (reverse video). ...
