fuser(1M)                      DG/UX R4.11MU05                     fuser(1M)


NAME
       fuser - identify processes using a file or file structure

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

DESCRIPTION
       Fuser lists the process ids of the processes using files.  Fuser does
       not identify processes on remote machines using files through NFS.
       For block special devices, all processes using any file on that
       device are listed.  The process ids are followed by c or r if the
       process is using the file as its current directory or its root
       directory and a t if the process is currently executing the file.

       If you use the -u option, the login name, in parentheses, also
       follows the process id.  In addition, if the -k option is specified,
       the SIGKILL signal is sent to each process.  Only a user with
       appropriate privilege (See NOTES, below) can terminate another user's
       process (see kill(2)).  The -F option matches any file on the same
       file system.  Options may be re-specified between groups of files.
       The new set of options replaces the old set; a single dash (-)
       cancels any 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.

EXAMPLES
       /etc/fuser -ku /dev/dsk/test
              If typed by a user with appropriate privilege (See NOTES,
              below), terminates all processes that are preventing the file
              system on the virtual disk named `test' from being unmounted
              and lists the process IDs and login name of each process as it
              is killed.

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

       /etc/fuser -ku /dev/dsk/test -u /etc/passwd
              Performs both of the first two examples in a single command
              line.

NOTES
       On a generic DG/UX system, appropriate privilege is granted by having
       an effective UID of 0 (root).  See the appropriate_privilege(5) man
       page for more information.

       On a system with DG/UX information security, appropriate privilege is
       granted by having one or more specific capabilities enabled in the
       effective capability set of the user.  See the cap_defaults(5) man
       page for more information.
