NAME

dp - parse dates 822-style

SYNOPSIS

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

DESCRIPTION

Dp is a program that parses dates according to the ARPA Internetstandard.It also understands many non-standard formats,such as those produced by TOPS-20 sites and some UNIX sites usingctime (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 822-format.Hence, it is usually best to enclose each argument in double-quotes for theshell.

To override the output format used by dp,the `-format string' or `-format file' switches are used.This permits individual fields of the address to be extracted with ease.The string is simply a format stringand thefile is simply a format file.See mh-format (5) for the details.

Here is the default format string used by dp:


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

which says that if an error was detected, print the error, a `:',and the date in error.Otherwise, output the 822-proper format of the date.^$HOME/.mh_profile~^The user profileNoneap(8)
Standard for the Format of ARPA Internet Text Messages (aka RFC-822)`-format' default as described above`-width' default to the width of the terminalNoneThe argument to the `-format' switch must be interpreted as a single tokenby the shell that invokes dp.Therefore,one must usually place the argument to this switch inside double-quotes.
