ali [-help] [-version] [-alias aliasfile] [-list | -nolist] [-user | -nouser] [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 entries.
By default, when an alias expands to multiple addresses, the addresses are separated by commas and printed on as few lines as possible. If the -list switch is specified, and an address expands to multiple addresses, each address will appear on a separate line.
The -user switch 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.
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).
Alias files are looked up in multiple locations: if the pathname is absolute or starts with “.” or “..” it is accessed directly; otherwise tilde expansion is done on usernames, then files are searched for in the user's Mail directory as specified in their profile. If not found there, the directory “/etc/nmh” is checked.
The user's profile.
