Example--Finding Out If a CD Is Still in Use

In the following example, the processes 6400c and 6399c are accessing the /cdrom/cdrom0 directory, and the process owners are root and smith, respectively.

# fuser -u /cdrom/cdrom0
/cdrom/cdrom0: 6400c(root)  6399c(smith)

You can kill the processes individually (as superuser), or you can use the fuser command with the -k option, which kills all the processes accessing that file system, as shown in the following example.

# fuser -u -k /cdrom/cdrom0
/cdrom/cdrom0: 6400c(root)Killed  6399c(smith)Killed
