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



NAME
     fuser - identify processes using a file or file structure

SYNOPSIS
     /usr/sbin/fuser [-[c|f]ku] files | resources [[-] [[c|f]ku]
     files | resources] . . .

DESCRIPTION
     fuser outputs the process IDs of the processes that are
     using the files or remote resources 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) its root directory, the code is
     r, 3) an open file, the code is o, or 4) its text file, the
     code is t.  For block special devices with mounted file sys-
     tems, all processes using any file on that device are
     listed.  For remote resource names, all processes using any
     file associated with that remote resource (Remote File Shar-
     ing) are reported. 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:

     -c   may be used with files that are mount points for file
          systems.  With that option the report is for use of the
          mount point and any files within that mounted file sys-
          tem.

     -m   synonymous to -c, is allowed for backwards compatibil-
          ity.

     -f   when this is used, the report is only for the named
          file, not for files within a mounted file system.

     -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.

     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

NOTE
     Because fuser works with a snapshot of the system image, it
     may miss processes that begin using a file while fuser is
     running.  Also, processes reported as using a file may have
     stopped using it while fuser was running.  These factors
     should discourage the use of the -k option.
