=head1 NAME

B<lat-pseudonyms> - The lazy administrator's tool to add pseudonyms

=head1 DESCRIPTION

Adds or deletes e-mail pseudonyms to existing user or group accounts on Mitel's SME servers (5.x/6.x).
This tool is functionally equivalent to the 'Pseudonyms' option in the server-manager, but can be run from the command line or called from an other script.
It allows you, for example, to create a large number of e-mail aliases in a batch process, or delete the standard pseudonyms on a remote machine via an ssh console.

See F</usr/doc/lazy-admin-tools/example.pseudonyms> for the format of the input file.

=head1 SYNOPSIS

B<lat-pseudonyms> -a -c "username | pseudonym1 | pseudonym2"

B<lat-pseudonyms> -a -i /path/to/quota.list

B<lat-pseudonyms> -d [-f] -c "user | pseudonym"

B<lat-pseudonyms> -d [-f] -i /path/to/quota.list

=head1 OPTIONS

The following options are supported:

=over 4

=item B<-a>, B<--add>

Add a pseudonym to a user or group.

=item B<-c "Arguments">, B<--command-line="Arguments">

Take arguments from the command line.
See the 'Arguments' section below for the various arguments that are accepted.

=item B<-d>, B<--delete>

Delete a pseudonym from the server

=item B<-f>, B<--force>

Don't prompt before deleting.

=item B<-h>, B<--help>

Extended help for this tool

=item B<-i FILE>, B<--input-file=FILE>

Use the information from FILE to create or delete the pseudonyms.

=back

=head2 Arguments:

   user*      : Must be a valid user or group on the server.
   pseudonym* : Must contain only lower-case letters, numbers,
                hyphens, arobase, periods and underscores, and should
                start with a lower-case letter.

   * mandatory field

=head1 EXAMPLES

B<lat-pseudonyms -a -c "harry | wizard | seeker |potter@existinglocaldomain.com">

Creates the pseudonyms 'wizard', 'seeker' and 'potter@existinglocaldomain.com'  for user 'harry'.

B<lat-pseudonyms -a -i /root/pseudonyms.list>

Creates the pseudonyms defined in F</root/pseudonyms.list>. Refer to F</usr/doc/lazy-admin-tools/example.users> for an example of an input file.

B<lat-pseudonyms -d -f -c "harry | wizard | seeker">

Deletes pseudonyms  'wizard' and 'seeker' from user 'harry'. The pseudonyms are deleted without prompting (-f).
