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 double−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 stringand thefile 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:

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.

Standard for the Format of ARPA Internet Text Messages
(RFC−822) ’−format’ defaults as
described above ’−normalize’
’−width’ defaults to the width of the
terminal None 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
double−quotes.
