Right now I am working on my thesis which is “Specializing Operating System Kernels using a Scripting Language”. A part of my work is porting the LuaJIT compiler into the FreeBSD x86 kernel.
When I was writing my thesis, I was asked to show modification information in the thesis.
They are number of lines added, numbers of lines removed, number of lines changed.
I know that diff exists. However, I need a summary of information produced by it.
My Google kung fu led me to diffstat.
It is very simple to use:
diff -u /path/to/luajit_kernel/src /path/to/luajit/src | diffstat -f0
The result is shown below.
