diff -ccommand, and are suitable for use with Larry Wall's Patch utility, available from SunSite.
It's actually a good idea to get and discard one patch immediately before you get the whole dictionary. That way the next patch you get will contain only the relevant changes.
After downloading the patch program, put it in the same directory as Dictionary. Download any patches into this same directory. Then run the command from within this directory:
patch -p1 < updateFile.txt(That's a one, not an L after -p). The Dictionary file must have no extension (e.g. .txt) for this to work.
rsync rsync://foldoc.org:8873/and to, e.g. copy the dictionary source to your /tmp directory:
rsync --times --progress rsync://foldoc.org:8873/foldoc/Dictionary /tmpSee the rsync documentation for details (run rsync with no arguments for a summary). Please let me know if you find it useful.
