[olug] Filesystems

[Chad Homan]

I believe a "mv" (which would maintain the original inode), then "cp" the
file back
to it's original name (new inode) should do the job.  My issue I would like
to avoid
renaming the entire filesystem.  Not to mention that I cannot remove the
original
file until after a reboot, in case the file is being used.  However, if I
could obtain
a "status" of the FS, My plans for world dominance would nearly be complete.
