The topic of debugging shell programs came up during the last talk, and
Eric mentioned the test harness urchin.

Here are some test suites written in urchin.

Urchin itself works under several shells.

Someone gave rave reviews of a shell linter. I think it was ShellCheck.
Either way, I have heard other rave reviews of ShellCheck.

In case nobody mentioned it, here are three neat debugging tools that
Ike showed me.

George lamented the difficulty of attracting young kids to simple,
stable, robust, non-hip software. My review of shell testing methods may
help in this aspect.
