Name
ap - parse addresses RFC 822-style
Syntax
/usr/lib/mh/ap [ -form file ] [ -format string ] [ -help ] [ -[no]normalize ] [ -width columns ] addrs ...
Description
The program 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 program treats each argument as one or more addresses, and prints those addresses in the official RFC 822 format. Hence, it is usually
best to enclose each argument in double quotes (") for the shell.
In addition to the standard escapes, also recognizes the additional escape error, which is a diagnostic that is returned if the parse
failed.
Options
-form file
Overrides the default output format of The output is formatted according to the instructions in the specified file. This must be
a format file; see
-format string
Overrides the default output format of The output is formatted according to the instructions in the specified string. This must
be a format string; see
The argument to the -format option must be interpreted as a single token by the shell that invokes Therefore, you should usually
place the argument to this option inside double quotes (").
-help Prints a list of the valid options to this command.
-normalize
-nonormalize
Tells to try to find the official host name of the address. This is the default behavior. It can be suppressed using the
-nonormalize option.
-width columns
Specifies the width of the screen in columns.
The defaults for this command are as follows:
-normalize
-width defaults to the width of the terminal
Restrictions
On systems where MH is configured with the BERK option, address parsing is not enabled.
Examples
This is the default format string used by
%<{error}%{error}: %{text}%|%(proper{text})%>
If an error was detected, this string instructs to print the error, a colon (:), and the address that is in error. Otherwise, output the
proper RFC 822 format of the address.
