lntree - link identical files in source trees
lntree [options] old-dir new-dir
Options: -[no]recurse recursive (enabled by default) -ident show identification -help brief help message
lntree will examine all files in two source trees and link the files that are equal. To be precise: if two files are equal (same size, same contents), the one in directory new-dir is replaced by a link to the file in old-dir.
This results in a substantial saving of disk space, for example when multiple versions of the same source tree need to be kept on-line. For best results, use the program like this:
lntree pkg-2.14 pkg-2.15 lntree pkg-2.15 pkg-2.16 lntree pkg-2.16 pkg-2.17
and so on.
Recurses through sub-directories. This is enabled by default.
Prints a brief help message and exits.
Prints program identification.
Some systems have a lndir command with different semantics. Make sure you are executing the right program!
