I have been responsible for Coverity tool integration/test/support in ALU LCP (Linux Control Platform) dept for nearly 2 years.  In this post, I would share a ksh tool/framework wrote on 2009 for Coverity modeling build automation. However, I would not involve too many things on Coverity itself (except the necessary background) but rather than some code examples to show one way to write multiple-choice menu via shell (如何用SHELL写多选菜单）- that’s is my point. Of course, if cmbat itself would give you a hint, thank God:)

Coverity: Coverity is a static code analysis tool developed by Coverity Inc. (It is said the biggest and strongest company on static code analysis. Another 2 famous ones you may heard of are Klocwork and Insure++)

Coverity modeling: Because of path limitation of analysis, some functions are unable to be analyzed. Coverity modeling is used to downsize these functions helping Coverity itself doing analysis on them. (There are also other usages on modeling, please refer to Coverity document. How to write Coverity modeling is not covered in this post the either way.)

cmbat: The basic idea is to construct modeling for some important functions (such as memory allocation/deallocation in our case). Then construct the corresponding modeling lib used by cmbat. The last thing is to write an automation tool (ksh in our case) according to your Coverity integration way. Again, please focus on the way to implement multiple-choice menu via shell.
