AIX Binaries I do not recommend that you use a pre-compiled lsof binary. It is better that you compile lsof for yourself from the distributed sources. Each AIX binary is stored in a subdirectory whose name is the AIX version. An AIX lsof lpp is available from: http://www-frec.bull.com/ Click: Downloadable resources from Bull -> Bull's Large Freeware and Shareware Archive for AIX(R) 4 AIX lsof binaries are available from: ftp://aixpdslib.seas.ucla.edu/pub/lsof There is no AIX 4.3.3 binary, because I no longer have access to an AIX 4.3.3 system.
