Testing bash

There are a series of tests that can be run on your newly built version of bash to see if it is running correctly. The tests are scripts that are derived from problems reported in earlier versions of the shell. Running these tests on the latest version of bash shouldn't cause any errors.

To run the tests just type make tests in the main bash directory. The name of each test is displayed, along with some warning messages, and then it is run. Successful tests produce no output (unless otherwise noted in the warning messages).

If any of the tests fail, you'll see a list of things that represent differences between what is expected and what happened. If this occurs you should file a bug report with the bash maintainer. See the Section 12.4.2 later in this chapter for information on how to do this.
