10.55. Diffutils-3.2

The Diffutils package contains programs that show the differences between files or directories.

10.55.1. Installation of Diffutils

Prepare Diffutils for compilation:

CC="gcc ${BUILD64}" ./configure --prefix=/usr

Diffutils wants ed as the default editor. The following sed will change the default to vim:

sed -i 's@\(^#define DEFAULT_EDITOR_PROGRAM \).*@\1"vi"@' lib/config.h

Compile the package:

make

To test the results, issue: make check.

Install the package:

make install

Installed programs: cmp, diff, diff3, and sdiff

cmp	Compares two files and reports whether or in which bytes they differ
diff	Compares two files or directories and reports which lines in the files differ
diff3	Compares three files line by line
sdiff	Merges two files and interactively outputs the results
