= suppressing shell debug output
Jenkins normally starts the shell to invoke a Fuego script by taking
the contents of the "Execute shell" command text box, putting it in
a temporary file, and executing it with "/bin/sh -xe /tmp/hudson..."
This makes it so that the shell echos every command it sees while it's
executing. In order to prevent this, you can specify the shell to run
yourself.

|
If the command text box contents has a first line that starts with #!,
then Jenkins will just execute that directly (instead of through its
own shell invocation. This means you can get rid of the -x parameter
to the shell by prefacing your text box contents with:
{{{#!YellowBox
#!/bin/sh -e
<rest of contents here>
}}}

If the first line of a shell build step starts with hashbang (#!),
then Jenkins will simply drop the script as is into a tmp file and
execute it.

And /bin/sh, is just the shell used by Jenkins by default. You can
change the default under Manage Jenkins -> Configure System.

= Jenkins supports matrix jobs =
Jenkins can run a matrix of jobs (where parameters are changed for each instance of what is essentially the same job). This is called a multi-configuration job.
