ap - parse addresses 822-style
/usr/lib/mh/ap [-form formatfile] [-format string] [-normalize |
-nonormalize] [-width columns] [-version] [-help] addrs ...
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 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
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:
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
$HOME/.mh_profile The user profile
/etc/nmh/mts.conf nmh mts configuration file
dp(8), Standard for the Format of ARPA Internet Text Messages (RFC-822)
`-format' defaults as described above
`-width' defaults to the width of the terminal
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.
