dates
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.
FLAGS
- -form file
-
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).
- -format
string-
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 (").
- -help
-
Prints a list of the valid options to this command.
- -width columns
-
Specifies the width of the screen in columns.
The defaults for this command are as follows:
-
-width
defaults to the width of the terminal
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.
