How do I see a list of open Files ?

[Joseph Scagluso]

I need to check if a file is open on an HP-UX 11.11 i server. Should I use 'sar' ?

[Jeff_Traigle]

Nope. You use "fuser" for that.

fuser -u file_path

This will report the PID and user that has the file open.

The standard UNIX tool is fuser but the best tool is "lsof" -- list open files. It's one of those tools that should be on every HP-UX box.

'lsof' is the tool!

In binary depot format as well as source.

If you are looking at a particular process, do "lsof -p process_id" to list the files opened by that process.

This displays all files - including the sockets open, etc.

Thanks, Guys...
