TABLE OF CONTENTS This appendix is a discussion of freeware tools available to assist with troubleshooting file system problems on a Tru64 UNIX system. These tools are available from different sites on the Internet, to which we have tried to provide pointers, when possible. Any well-managed Tru64 UNIX system will have these tools installed and use them on a regular basis.
This utility is probably the most useful freeware tool for troubleshooting file system issues on any UNIX system, but in Tru64 in particular.

Lsof does this in a much more readable fashion than does fuser(8). You'll also find that the documentation that comes with lsof should answer most of your questions.
If you are looking for the latest distributed version of this tool, it is available via anonymous ftp from the host vic.cc.purdue.edu. You'll find the lsof distribution in the pub/tools/unix/lsof directory. If you want to use your web browser, that URL is:
ftp://vic.cc.purdue.edu/pub/tools/unix/lsof
What you will discover if you go to that site is source code that you can easily compile and install yourself. In addition, you will also find binaries for...
