dp(8) System Manager's Manual dp(8)
NAME
dp - parse dates RFC 822-style
SYNOPSIS
/usr/lib/mh/dp [-form file] [-format string] [-help] [-width columns] dates
OPTIONS
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
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
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.
