Hi Grant,

I love lsof.

When you run lsof as root does it list all files open by all processes?

I take it you are trying to use lsof to check if any processes have the
file open for writing, so you can copy the file when it's all done.
Just so we are on the same page could you please specify the following:

1. full permissions & ownership of lsof binary
2. full uid/gid of user running lsof
3. permissions & ownership of the files that you want to copy

I'm not sure about RHEL3 but was wondering if you have any SELinux type
extensions or functionality in your kernel?
