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 use- ful 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 usu- ally 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. FILES
$HOME/.mh_profile The user profile /etc/nmh/mts.conf nmh mts configuration file PROFILE COMPONENTS
None SEE ALSO
dp(8), Standard for the Format of ARPA Internet Text Messages (RFC-822) DEFAULTS
`-format' defaults as described above `-normalize' `-width' defaults to the width of the terminal 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. MH.6.8 11 June 2012 AP(8)
