fuser(1M)                                               fuser(1M)



NAME
     fuser - identifies processes using a file or file structure

SYNOPSIS
     fuser [-] [-k] [-nnamelist] [-u] file...

ARGUMENTS
     -    Cancels any options currently in force before
          specifying a new group of files.

     file ...
          Specifies the file used as the argument when
          processing.

     -k   Sends the SIGKILL signal to each process.  Only the
          superuser can terminate another user's process (see
          kill(2)).

     -nnamelist
          Specifies an alternate namelist (/unix is the default).

     -u   Indicates that the login name, in parentheses, also
          follows the process ID.

DESCRIPTION
     fuser lists the process IDs of the processes using the files
     specified as arguments.  For block special devices, it lists
     all processes using any file on that device.  The process ID
     is followed by c, p, or r if the process is using the file
     as its current directory, the parent of its current
     directory (only when in use by the system), or its root
     directory, respectively.

     You can respecify options between groups of files.  The new
     set of options replaces the old set.

     The process IDs are printed as a single line on the standard
     output, separated by spaces and terminated with a single new
     line.  All other output is written on standard error.

EXAMPLES
     fuser -ku /dev/dsk/c1d0s0
          allow the superuser to terminate all processes
          preventing disk drive one from being unmounted.  List
          the process ID and login name of each as it is killed.

     fuser -u /etc/passwd
          list process IDs and login names of processes that have
          the password file open.

     fuser -ku /dev/dsk/c1d0s0 -u /etc/passwd
          will do both of the above examples in a single command
