Hi, apparently diff caches stuff in memory.
I noticed that when I wanted to make a patch with diff -urN clean_dir patched_dir > my_patch The patch came out fine, but then I realized that clean_dir wasn´t really clean, so I made a new clean version *with the same* directory name. The second time I ran diff it went really fast. Too fast: it didn´t examine the files in clean_dir at all, it just used the data from the previous run which it had cached, so my patch was the same as before (wrong). How can I get diff to forget what it saw? The manpage doesn´t tell me. (I didn´t think about `touch'ing the directory then, but I untarred clean_dir from a tarball, so it should have gotten a newer time stamp). TIA, Colin -- | Re: Kernel size is 666K!
