Diffstat

Diffstat is an open source command-line software that reads the output of the diff command and displays a histogram of the deletions, modifications and insertions in each file.

Diffstat is commonly used on Linux/UNIX operating systems to provide a summary of the changes in large and complex patch files.

Usage: diffstat [options] [files]

The program will read from one or more input files that contain output from the diff command, generating a histogram of total lines changed for each file referenced.

However, keep in mind that If no filename is given on the command-line, Diffstat will automatically read from standard input.
