NAME    [Toc]    [Back]

       dp - parse dates RFC 822-style

SYNOPSIS    [Toc]    [Back]

       /usr/lib/mh/dp   [-form  file]  [-format  string]  [-help]
       [-width columns] dates

OPTIONS    [Toc]    [Back]

       Overrides the default output format of dp.  The output  is
       formatted  according  to the instructions in the specified
       file.  This must  be  a  format  file;  see  mh-format(4).
       Overrides  the default output format of dp.  The output is
       formatted according to the instructions in  the  specified
       string.  This must be a format string; see mh-format(4).

              The  argument  to the -format option must be interpreted
 as a single token by the shell that  invokes
              dp.  Therefore,  you should usually place the argument
 to  this  option  inside  double  quotes  (").
              Prints a list of the valid options to this command.
              Specifies the width of the screen in columns.

       The defaults for this command are as follows:

       -width  defaults to the width of the terminal

DESCRIPTION    [Toc]    [Back]

       The dp command parses dates according to the ARPA Internet
       standard.   It also understands many non-standard formats,
       such as those produced by  TOPS-20  sites  and  some  UNIX
       sites  using ctime(3). It is useful for seeing how MH will
       interpret a date.

       The dp program treats each argument as a single date,  and
       prints the date out in the official RFC 822 format. Hence,
       it is usually best to  enclose  each  argument  in  double
       quotes (") for the shell.

EXAMPLES    [Toc]    [Back]

       This is the default format string used by dp:

       %<(nodate{text})error: %{text}%|%(pretty{text})%>

       When an error is detected, this prints error: and the date
       that is in error. Otherwise, it outputs the proper RFC 822
       format of the date.
