FUSER(1M)                                               FUSER(1M)



     NAME
          fuser - identify processes using a file or file structure

     SYNOPSIS
          /etc/fuser [-ku] files [-] [[-ku] files]

     DESCRIPTION
          fuser outputs the process IDs of the processes that are
          using the files specified as arguments.  Each process ID is
          followed by a letter code, interpreted as follows:  if the
          process is using the file as 1) its current directory, the
          code is c, 2) the parent of its current directory (only when
          the file is being used by the system), the code is p, or 3)
          its root directory, the code is r.  For block special
          devices with mounted file systems, all processes using any
          file on that device are listed.

          The following options may be used with fuser:

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

          -k   the SIGKILL signal is sent to each process.  Since this
               option spawns kills for each process, the kill messages
               may not show up immediately [see kill(2)].

          If more than one group of files are specified, the options
          may be respecified for each additional group of files.  A
          lone dash cancels the options currently in force; then, the
          new set of options applies to the next group of files.

          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.

          Any user with permission to read /dev/kmem and /dev/mem can
          use fuser.  Only the super-user can terminate another user's
          process.

     FILES
          /unix        for system namelist
          /dev/kmem    for system image
          /dev/mem     also for system image
