fuser(8) System Administration Commands fuser(8)
NAME
fuser - identify users of files and devices
SYNOPSIS
/usr/sbin/fuser [-c | -d | -f] [-nu] [-k | -s sig] files
[ [-] [-c | -d | -f] [-nu] [-k | -s sig] files] ...
DESCRIPTION
The fuser utility 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 direc‐
tory
e Indicates that the process is monitoring the file for file events.
For more information, see the port_associate(3C) man page
m Indicates that the process is using a file mapped with mmap(2).
See mmap(2) for details.
n Indicates that the process is holding a non-blocking mandatory
lock on the file
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 us‐
ing any file on that device are listed. For all types of files (text
files, executables, directories, devices, and so forth), only the
processes using that file are reported.
For all types of devices, fuser also displays any known kernel con‐
sumers that have the device open. Kernel consumers are displayed in one
of the following formats:
[module_name]
[module_name,dev_path=path]
[module_name,dev=(major,minor)]
[module_name,dev=(major,minor),dev_path=path]
If more than one group of files are specified, the options may be re‐
specified 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. All other output, including the single terminating
newline, is written on standard error.
Any user can run fuser, but the {PRIV_PROC_OWNER} privilege is required
to send a signal to another user's process.
OPTIONS
The following options are supported:
-c Reports on files that are mount points for file systems, and
any files within that mounted file system.
-d Report device usage information for all minor nodes bound to
the same device node as the specified minor node. This option
does not report file usage for files within a mounted file
system.
-f Prints a report for the named file, not for files within a
mounted file system
-k Equivalent to -s KILL or -s 9.
-l Prevents resolving the symlinks to target file
-n Lists only processes with non-blocking mandatory locks on a
file
-s sig Sends a signal to each process. The sig option argument spec‐
ifies one of the symbolic names defined in the <signal.h>
header, or a decimal integer signal number. If sig is a sym‐
bolic name, it is recognized in a case-independent fashion,
without the SIG prefix. No signals will be sent to kernel
file consumers or file event monitors. For more information,
see the kill(2) and signal.h(3HEAD) man pages.
-u Displays the user login name in parentheses following the
process ID.
EXAMPLES
Example 1 Reporting on the Mount Point and Files
The following example reports on the mount point and files within the
mounted file system.
example% fuser -c /export/foo
Example 2 Restricting Output when Reporting on the Mount Point and
Files
The following example reports on the mount point and files within the
mounted file system, but the output is restricted to processes that
hold non-blocking mandatory locks.
example% fuser -cn /export/foo
Example 3 Sending SIGTERM to Processes Holding a Non-blocking Mandatory
Lock
The following command sends SIGTERM to any processes that hold a non-
blocking mandatory lock on file /export/foo/my_file.
example% fuser -fn -s term /export/foo/my_file
ENVIRONMENT VARIABLES
See environ(7) for descriptions of the following environment variables
that affect the execution of fuser: LANG, LC_ALL, LC_CTYPE, LC_MES‐
SAGES, and NLSPATH.

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.
