       rushwho  [-Hh]  [-F STRING] [-f DIR] [--file=DIR] [--format=STRING] [--help] [--no-header]
       [--usage] [--version]


       This manpage is a short description of rushwho.   For  a  detailed  discussion,  including
       examples  and  usage  recommendations,  refer  to the manual GNU Rush -- a restricted user
       shell, available in texinfo format.  If the info reader and  the  rush  documentation  are
       properly installed on your system, the command

           info rushwho

       should give you access to the complete manual.

       You  can  also  view  the  manual  using  the info mode in emacs(1), or find it in various
       formats online at


       If any discrepancies occur between this  manpage  and  the  Manual,  the  later  shall  be
       considered the authoritative source.


       Displays  a list of users who are currently logged in by rush(1).  The utility operates on
       the default accounting database, which is maintained if rush(1) runs in accounting mode.


       -F, --format=STRING
              Use STRING instead of the default format.  See the section FORMAT, for  a  detailed
              discussion  of  the  format  syntax.   If  the  STRING  begins  with a @, then this
              character is removed from it, and the resulting string is regarded as a name of the
              file  to  read.   The  file  is  read literally, except that lines beginning with a
              semicolon are ignored.

       -f, --file=DIR
              Look for database files in DIR.

       -n, --count=NUMBER
              Show at most NUMBER records.

       Other options

       -h, --help
              Give this help list.

              Give a short usage message.

              Print program version.


              When set, supplies a format string to use instead of the built-in format.   If  the
              value  begins  with  a @ sign, rest of characters is treated as the name of file to
              read the format from, similarly to the --format option, which see.

              The precedence rule for format selection is:

              1.     The --format option.

              2.     The RUSHWHO_FORMAT environment variable.

              3.     Built-in format.


       The format string supplied with the -F (--format) option  controls  the  output  of  every
       record  from  the  GNU  Rush accounting database.  It consists of the following classes of

       Ordinary characters
              These are copied to the output verbatim.

              An escape is a backslash, followed  by  a  single  character.   It  is  interpreted
              according to the following table:

                      Sequence    Replaced with
                      \a          Audible bell character (ASCII 7)
                      \b          Backspace character (ASCII 8)
                      \e          Escape character (ASCII 27)
                      \f          Form-feed character (ASCII 12)
                      \n          Newline character (ASCII 10)
                      \r          Carriage return character (ASCII 13)
                      \t          Horizontal tabulation character (ASCII 9)
                      \v          Vertical tabulation character (ASCII 11)
                      \\          A single backslash
                      \"          A double-quote.

              Any  escape  not  listed  in  the table above results in its second character being

       Quoted strings
              Strings are delimited by single or double quotes.  Within a string escape sequences
              are interpreted as described above.

       Format specifications
              Format  specification  can  be  regarded  as  a  kind  of function, which outputs a
              particular piece of information from the database  record.   Syntactically,  format
              specification  starts  with  an  opening  brace and ends with a closing brace.  The
              first word after the brace is the name of the specification.  The rest of words are
              positional  arguments followed by keyword arguments.  Both are optional.  A keyword
              argument begins with a colon.

       The available format specifications are:

       (newline [COUNT])
              Causes the newline character to be output.  If the optional count is supplied, that
              many newlines will be printed

       (tab [COUNT])
              Advance  to  the next tab stop in the output stream.  If optional COUNT is present,
              then skip that many tab stops.  Each tab stop is eight characters long.

       The following specifications output particular fields of a database record.  They all take
       two positional arguments: WIDTH and TITLE.

       The  first  argument, WIDTH sets the maximum output length for this specification.  If the
       number of characters actually output is less than the width,  they  will  be  padded  with
       whitespace  either  to  the  left or to the right, depending on the presence of the :right
       keyword argument.  If the number of  characters  is  greater  than  WIDTH,  they  will  be
       truncated to fit.  If WIDTH is not given, the exact data are output as is.

       The  second  argument,  TITLE,  gives  the  title of this column for the heading line.  By
       default no title is output.

       Every field specification accepts at least two keyword arguments.  The keyword :right  may
       be  used to request alignment to the right for the data.  This keyword is ignored if WIDTH
       is not given.

       The keyword :empty followed by a string causes the program to output that  string  if  the
       resulting value for this specification would otherwise be empty.

       (user WIDTH TITLE [:empty REPL][:right])
              Print the user login name.

       (time WIDTH TITLE [:empty REPL][:right][:format DATE-FORMAT])
              Date and time when the session started.  The word start-time can be used instead of

              The :format keyword introduces the  strftime(3)  format  string  to  be  used  when
              converting the date for printing.  The default value is "%a %H:%M".

       (duration WIDTH TITLE [:empty REPL][:right])
              Total time of the session duration.

       (rule WIDTH TITLE [:right])
              The tag of the rule that was used to serve the user.

       (command WIDTH TITLE [:empty REPL][:right])
              Command line being executed.

       (pid WIDTH TITLE [:right])
              PID of the process.

       For  example,  the  following is the default format for rushwho.  It is written in a form,
       suitable for use in a file supplied with the --format=@FILE option:

       (user 10 Login)" "
       (rule 8 Rule)" "
       (start-time 0 Start)" "
       (duration 9 Time)" "
       (pid 10 PID)" "
       (command 28 Command)


       rush(1), rushwho(1).
