Lsof 3.41 is now the current distribution on vic.cc.purdue.edu in pub/tools/unix/lsof. This revision of lsof uses a private device cache file for each UID that executes lsof. The world-readable and world-writable /tmp/.lsof_dev_cache file is no longer used. The documentation in the release notes (00DIST, 00FAQ, and 00README), the man page, and the source code give details. Lsof 3.41 has new support for IRIX 6.1 and Linux up through 1.3.20, but I've been advised lsof 3.41 doesn't compile under Linux 1.3.22. I thank the "gentle readers" of this list for their useful suggestions. Vic Abell <abe@cc.purdue.edu>, lsof author
