open files 1

[apocalypse11]

I have a linux server and access files via samba. when a user says there is a "file locked for editing" how can i find out exactly who the user is on the system that has the file open at that time - from the server side.

THanks

man lsof
man fuser

can anyone elaborate on how to use these commands?

If you know the directory and filename on the Linux box, change to that directory and type: (don't include the {} brackets)

# fuser {filename}

You'll get the PID (Process ID) of the process which has the file open. You can then run:

# ps -ef | grep {PID}

On some (most?) versions, you can also just type:

# fuser -u {filename}

This should present both the PID and the UserID.

man works by typing "man" followed by the name of a command you are interested in learning about.

ex.
man fusuer

This will display information about 'fuser' command.

ex.
man lsof

This will display information about the 'lsof' command.

ex.
man man

This will display information about the 'man' command.

It's quite the useful utility, you should use it.
