This is 'lntree', a tool to compare directory trees. 'lntree old-dir new-dir' recursively examines all files in the 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 cleaner source trees, and a substantial saving of disk space, for example when multiple versions of the same source tree need to be kept on-line. To install, unpack the kit, change to the kit directory, and execute perl Makefile.PL make make install Note that the last command usually requires root privilege. ---------------------------------------------------------------------------- Johan Vromans jvromans@squirrel.nl Squirrel Consultancy Haarlem, the Netherlands http://www.squirrel.nl http://www.squirrel.nl/people/jvromans PGP Key 2048/4783B14D http://www.squirrel.nl/people/jvromans/pgpkey.html ----------------------- "Arms are made for hugging" ------------------------
