NAME

       ap - parse addresses 822-style

SYNOPSIS

       /usr/lib/mh/ap [-form formatfile] [-format string] [-normalize | -nonormalize] [-width
            columns] [-version] [-help] addrs ...

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 nmh will interpret an
       address.

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

       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(5)
       for the details.

       In addition to the standard escapes, ap also recognizes the following additional escape:

            Escape  Returns  Description
            error   string   A diagnostic 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}%|%(putstr(proper{text}))%>

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

       `-format' defaults as described above
       `-normalize'

CONTEXT

       None

BUGS

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