FUSER(1M-SysV)      RISC/os Reference Manual       FUSER(1M-SysV)



NAME
     fuser - identify processes using a file or file structure

SYNOPSIS
     /etc/fuser [-kmu] files [-] [[-kmu] 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, or 2) its root directory, the code is r.  For
     block special devices associated with mounted file systems,
     and for file system mount points when the -m option is
     specified, all processes using any file on the mounted file
     system are listed.  For all other types of files (text
     files, executables, directories, devices, etc.) only the
     processes using that file are reported.

     The following options may be used with fuser:

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

     -m   the file is interpreted as a file system mount point.
          With this option, the file is required to be either a
          file system mount point or a block special device asso-
          ciated with a mounted file system.

     -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
