tomahawk Recipes

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 a file in remote hosts is all the same

At first, copy a file to be compared to remote hosts.

$ tomahawk-rsync -h <hosts> /usr/local/apache2/conf/httpd.conf /tmp/httpd.conf

And then, diff 2 files with -V (–verify-output) option.

$ tomahawk -h <hosts> -V 'diff /tmp/httpd.conf /usr/local/apache2/conf/httpd.conf
...
[error] Detected different command output on following hosts.
...

Omit command line options by –conf option

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.

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

It is good to define commonly-used options in a configuration file.
