fuser

Synopsis

fuser [options] [files | filesystems]

Identifies and outputs the process IDs of processes that are using the files or local filesystems. Each process ID is followed by a letter code: c if process is using file as the current directory; e if executable; f if an open file; F if open file for writing; 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. Like a number of other administrator commands, fuser is usually installed to the /sbin directory. You may need to add that directory to your path or execute the command as /sbin/fuser.
