NAME

ap − parse addresses RFC 822-style

SYNTAX

/usr/new/lib/mh/ap [−form formatfile] [−format string] [−normalize] [−nonormalize] [−width columns] addrs ...  [−help]

DESCRIPTION

ap is a program that parses addresses according to the ARPA Internet standard. It also understands many non-standard formats. It is useful for seeing how MH will interpret an address.

The ap program treats each argument as one or more addresses, and prints those addresses out in the official RFC 822-format. Hence, it is usually best to enclose each argument in quotes for the shell.

OPTIONS

To override the output format used by ap, 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 string and the file is simply a format file.  See mh−format() for the details.

In addition to the standard escapes, scan also recognizes the following additional escape: error, which is a diagnostic that is returned if the parse failed. 

If the −normalize switch is given, ap will try to track down the official hostname of the address.

Here is the default format string used by ap:

%<{error}%{error}: %{text}%|%(proper{text})%>

which says that if an error was detected, print the error, a colon (:), and the address in error.  Otherwise, output the RFC 822-proper format of the address. 

The argument to the −format switch must be interpreted as a single token by the shell that invokes ap. Therefore, you should usually place the argument to this switch inside quotes.

DEFAULTS

−format defaults as described above
−normalize
−width defaults to the width of the terminal

RESTRICTIONS

On systems where MH was configured with the BERK option, address parsing is not enabled.  The version of MH that is supplied with ULTRIX Mail Connection has the BERK option enabled.
