## Order your minions around

Now that you have a master and at least one minion communicating with each other you can perform commands on the minion via the salt command. Salt calls are comprised of three main components:

    salt '<target>' <function> [arguments]

salt manpage

### target

The target component allows you to filter which minions should run the following function. The default filter is a glob on the minion id. For example:

    salt '*' test.ping
    salt '*.example.org' test.ping

Targets can be based on minion system information using the Grains system:

    salt -G 'os:Ubuntu' test.ping

Grains system

Targets can be filtered by regular expression:

    salt -E 'virtmach[0-9]' test.ping

Targets can be explicitly specified in a list:

    salt -L 'foo,bar,baz,quo' test.ping

Or Multiple target types can be combined in one command:

    salt -C 'G@os:Ubuntu and webser* or E@database.*' test.ping

### function

A function is some functionality provided by a module. Salt ships with a large collection of available functions. List all available functions on your minions:

    salt '*' sys.doc

Here are some examples:

Show all currently available minions:

    salt '*' test.ping

Run an arbitrary shell command:

    salt '*' cmd.run 'uname -a'

### arguments

Space-delimited arguments to the function:

    salt '*' cmd.exec_code python 'import sys; print sys.version'

Optional, keyword arguments are also supported:

    salt '*' pip.install salt timeout=5 upgrade=True

They are always in the form of `kwarg=argument`.

Current Salt release: 0.17.1
