Each process ID is followed by a letter code: c if process is using file as current directory, e if executable, f if an open file, m if a shared library, and r if the root directory. Any user with permission to read /dev/kmem and /dev/mem can use fuser, but only a privileged user can terminate another user's process. fuser does not work on remote (NFS) files. If more than one group of files is specified, the options may be respecified for each additional group of files. A lone dash (-) cancels the options currently in force, and the new set of options applies to the next group of files. Linux Commands Options
