How do I see how much space I'm using?

How do I set my prompt to show the current working directory or something like that?

Example:

From the tcsh manual page:

       prompt  The  string  which  is printed before reading each command from
               the terminal.  prompt may include any of the following  format-
               ting  sequences  (+),  which are replaced by the given informa-
               tion:

               %/  The current working directory.
               %~  The current working directory, but with one's  home  direc-
                   tory  represented  by `~' and other users' home directories
                   represented  by  `~user'  as  per  Filename   substitution.
                   `~user'  substitution happens only if the shell has already
                   used `~user' in a pathname in the current session.
               %c[[0]n], %.[[0]n]
                   The trailing component of the current working directory, or
                   n  trailing  components if a digit n is given.  If n begins
                   with `0', the number  of  skipped  components  precede  the
                   trailing  component(s)  in the format `/trailing'.
                   If the ellipsis shell variable is set,  skipped  components
                   are  represented  by  an  ellipsis  so  the  whole  becomes
                   `...trailing'.  `~' substitution is done as in `%~'  above,
                   but  the  `~'  component  is ignored when counting trailing
                   components.
               %C  Like %c, but without `~' substitution.
               %h, %!, !
                   The current history event number.
               %M  The full hostname.
               %m  The hostname up to the first `.'.
               %S (%s)
                   Start (stop) standout mode.
               %B (%b)
                   Start (stop) boldfacing mode.
               %U (%u)
                   Start (stop) underline mode.
               %t, %@
                   The time of day in 12-hour AM/PM format.
               %T  Like `%t', but in 24-hour format (but see  the  ampm  shell
                   variable).
               %p  The  `precise'  time  of  day in 12-hour AM/PM format, with
                   seconds.
               %P  Like `%p', but in 24-hour format (but see  the  ampm  shell
                   variable).
               \c  c is parsed as in bindkey.
               ^c  c is parsed as in bindkey.
               %%  A single `%'.
               %n  The user name.
               %j  The number of jobs.
               %d  The weekday in `Day' format.
               %D  The day in `dd' format.
               %w  The month in `Mon' format.
               %W  The month in `mm' format.
               %y  The year in `yy' format.
               %Y  The year in `yyyy' format.
               %l  The shell's tty.
               %L  Clears  from the end of the prompt to end of the display or
                   the end of the line.
               %$  Expands the shell or environment variable name  immediately
                   after the `$'.
               %#  `>'  (or the first character of the promptchars shell vari-
                   able) for normal users, `#' (or  the  second  character  of
                   promptchars) for the superuser.
               %{string%}
                   Includes string as a literal escape sequence.  It should be
                   used only to change terminal attributes and should not move
                   the  cursor  location.  This cannot be the last sequence in
                   prompt.
               %?  The return code of the command  executed  just  before  the
                   prompt.
               %R  In prompt2, the status of the parser.  In prompt3, the cor-
                   rected string.  In history, the history string.

               `%B', `%S', `%U' and `%{string%}' are available in only  eight-
               bit-clean shells; see the version shell variable.

               The  bold,  standout  and underline sequences are often used to
               distinguish a superuser shell.  For example,

                   > set prompt = "%m [%h] %B[%@]%b [%/] you rang? "
                   tut [37] [2:54pm] [/usr/accts/sys] you rang? _

               If `%t', `%@', `%T', `%p', or `%P' is used, and noding  is  not
               set,  then print `DING!' on the change of hour (i.e, `:00' min-
               utes) instead of the actual time.

               Set by default to `%# ' in interactive shells.
