Describes how to use tomahawk.

Formatting output

-F/--output-format option can change tomahawk’s output.

$ tomahawk -h <hosts> -F '[${host}] ${output}' -h <hosts> 'date'

[localhost] Sat Jun  2 02:21:39 JST 2012
[127.0.0.1] Sat Jun  2 02:21:40 JST 2012

You can speficy following variables.

• ${user}
• ${host}
• ${command}
• ${output}

Checking files on remote hosts

Since v0.6.0, able to check files on remote hosts are all the same. Let’s check httpd.conf is all the same with md5sum command.

$ tomahawk -h <hosts> -V 'md5sum /usr/local/apache2/conf/httpd.conf'

If output of some hosts are different, you’ll get following errors.

...
[error] Detected different command output on following hosts.
...

Omit command line options by a configuration file.

Since v0.6.0, you can omit command line options by a configuration file. If -c/--conf option is specified, tomahawk and tomahawk-rsync read command line options from a configuration file. It is good to define commonly-used options in a configuration file.

Configuration file is just ini file like below.

[tomahawk]
options = --parallel 1

[tomahawk-rsync]
options = --parallel 1

That is equivalent to

$ tomahawk --parallel 1
$ tomahawk-rsync --parallel 1
