Lowest Common Denominator

This is a small utility that reports the lowest common denominator in two paths.

./lcd 
Usage: ./lcd [-r] <path1> <path2>

Examples

./lcd /long/path/to/some/file /long/path/to/some/other/file 
/long/path/to/some/

./lcd -r /long/path/to/some/file /long/path/to/some/other/file 
other/file

Notice that the reversed (-r) option reports the part of path2 that differs from path1.

Build

Download the source-code and build it using:

gcc -o lcd lowest-common-denominator.c
