NAME
      fuser - identify processes using a file or file structure
 


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


DESCRIPTION
      fuser displays the process IDs of  the  processes  that  are
      using the files specified as arguments.
 
      Each process  ID is followed by a letter code.  These letter
      codes  are  interpreted  as follows: if the process is using
      the file as
 
      c     Indicates that the process is using the  file  as  its
            current directory.
 
      m     Indicates that the process is using a file mapped with
            mmap(2). See  mmap(2) for details.
 
      o     Indicates that the process is using  the  file  as  an
            open file.
 
      r     Indicates that the process is using the  file  as  its
            root directory.
 
      t     Indicates that the process is using the  file  as  its
            text file.
 
      y     Indicates that the process is using the  file  as  its
            controlling terminal.
 
      For block special devices with  mounted  file  systems,  all
      processes  using any file on that device are listed. For all
      types of files (text files, executables,  directories,  dev-
      ices, and so forth), only the processes  using that file are
      reported.
 
      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 can run fuser, but only the superuser can terminate
      another user's process.

OPTIONS
      The following options are supported:
 
      -c    Reports on files that are mount points for  file  sys-
            tems, and any files within that mounted file system.
 
      -f    Print a report for  the  named  file,  not  for  files
            within a mounted file system.
 
      -k    Sends the  SIGKILL signal to each process. Since  this
            option  spawns  kills  for each process, the kill mes-
            sages may not show up immediately (see kill(2)).
 
      -u    Displays the user login name in parentheses  following
            the process ID.
 
 ENVIRONMENT VARIABLES
      See  environ(5) for descriptions of the  following  environ-
      ment  variables  that  affect the execution of  fuser: LANG,
      LC_ALL LC_CTYPE, LC_MESSAGES, and NLSPATH.

      butes:

NOTES
      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.
