* Remote systems can be divided into hostgroups (e.g. web and db) by
|
||||
prepending '@groupname/' to the sshlogin. Multiple groups can be
|
||||
given by separating groups with '+'. E.g. @web/www1 @web+db/www2
|
||||
@db/mariadb
|
||||
|
||||
* Remote execution can be restricted to servers that are part of one
|
||||
or more groups by '@groupname' as an sshlogin. Multiple groups can
|
||||
be given by separating groups with '+'. E.g. -S @web or -S @db+web
|
||||
|
||||
* With --hostgroup you can restrict arguments to certain hostgroups by
|
||||
appending '@groupname' to the argument. Multiple groups can be
|
||||
given by separating groups with '+'. E.g. my_web_arg@web
|
||||
db-or-web-arg@db+web db-only-arg@db Thanks to Michel Courtine for
|

developing a prototype for this.
