ali - list mail aliases
ali [-alias aliasfile] [-list | -nolist] [-normalize | -nonormalize]
[-user | -nouser] [-version] [-help] [aliases ...]
Ali searches the named mail alias files for each of the given aliases.
It creates a list of addresses for those aliases, and writes that list
on standard output. If no arguments are given, ali outputs all alias
By default, when an aliases expands to multiple addresses, the
addresses are separated by commas and printed on as few lines as
possible. If the -list option is specified, then when an address
expands to multiple addresses, each address will appear on a separate
The switch -user directs ali to perform its processing in an inverted
fashion: instead of listing the addresses that each given alias expands
to, ali will list the aliases that expand to each given address. If
the -normalize switch is given, ali will try to track down the official
hostname of the address.
The files specified by the profile entry “Aliasfile” and any additional
alias files given by the -alias aliasfile switch will be read. Each
alias is processed as described in mh-alias(5).
$HOME/.mh_profile The user profile
/etc/passwd List of users
/etc/group List of groups
Path: To determine the user’s nmh directory
Aliasfile: For a default alias file
‘aliasfiles’ defaults to /etc/nmh/MailAliases
The -user option with -nonormalize is not entirely accurate, as it does
not replace local nicknames for hosts with their official site names.
