Installing Diffutils

Installation of Diffutils

root:diffutils-2.7# make LDFLAGS=-static
root:diffutils-2.7# make prefix=$LFS/usr install


The Diffutils packagec contains the cmp, diff, diff3 and sdiff programs.


cmp and diff

cmp and diff both compare two files and report their differences. Both programs have extra options which compare files in different situations.


The difference between diff and diff3 is that diff comprares 2 files, diff3 compares 3 files.


sdiff merges two two files and interactively outputs the results.
