ALI(1) [nmh-1.5] ALI(1)
NAME
ali - list mail aliases
SYNOPSIS
ali [-alias aliasfile] [-list | -nolist] [-normalize | -nonormalize] [-user | -nouser] [-version] [-help] [aliases ...]
DESCRIPTION
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 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 line.
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).
FILES
$HOME/.mh_profile The user profile
/etc/passwd List of users
/etc/group List of groups
PROFILE COMPONENTS
Path: To determine the user's nmh directory
Aliasfile: For a default alias file
SEE ALSO
mh-alias(5)
DEFAULTS
`aliasfiles' defaults to /etc/nmh/MailAliases
`-nolist'
`-nonormalize'
`-nouser'
CONTEXT
None
BUGS
The -user option with -nonormalize is not entirely accurate, as it does not replace local nicknames for hosts with their official site
names.
