see who is currently using a file

[AP81]

I have a RedHat fileserver set up with samba to allow 30+ people on our network to access the files on that machine.

What I want to be able to do is to be able to check whether a specific file is currently in use, and even better, who (which user on the network) is using it.

Is there any way to do this via the terminal or by the use of a third-party software tool? Any help or input is appreciated.

Thanks in advance.

there is a freeware utility lsof (list open files) (I have this on Solaris, but I think it comes from the freebsd/lunix world); this will show you the PID of the process (ie. the samba process) who has an open filehandle.

To find out the user who has opened this file will be a samba issue...

for SMB connections, try:

smbstatus -d

This will list all the opened files and what PIDs are using them.

The 'finger' command is also useful to get info about certain users.
Check the MAN page out.
