Script was tested with FreeBSD /bin/sh and AT&T ksh93 from ports. # This is a shell archive. Save it in a file, remove anything before # this line, and then unpack it by entering "sh file". Note, it may # create directories; files and directories will be owned by you and # have default permissions. # # This archive contains: # # fuser.1 # fuser.sh # echo x - fuser.1 sed 's/^X//' >fuser.1 << 'END-of-fuser.1' X.\" Copyright (c) 2002 Tim J.

X.Pp XIf a X.Ar file Xargument is a block special device, all processes using any file on that Xdevice are listed. X.Pp XAdditional information about the open files is written to standard error. X.Pp XThe options are as follows: X.Bl -tag -width indent X.It Fl M Ar core XExtract values associated with the name list from X.Ar core Xinstead of X.Pa /dev/kmem . X.It Fl N Ar system XExtract the name list from X.Ar system Xinstead of X.Pa /kernel . X.It Fl c XTreat the X.Ar file Xarguments as mount points and list all files open on these file systems. X.It Fl f XDisable special processing for block special devices. X.It Fl m XInclude information about memory mapped files. X.It Fl u XInclude the user who owns each process in the output. X.El X.Pp XThe format of the output is: X.Bl -bullet -offset indent X.It XFile or mount point name, followed by a colon X.Pq Ql \&: ; X.It XProcess ID; X.It XZero or more of the following flags, indicating how the file is being used: X.Bl -tag -width z X.It Cm c XProcess's working directory X.It Cm r XProcess's root directory X.It Cm x XExecutable text X.It Cm t XKernel trace file X.It Cm m XMemory mapped file X.El X.It XIf the X.Fl u Xoption is given, the user name of the process's owner, in parentheses. X.El X.Sh EXAMPLES XKill all processes with X.Pa foo.c Xopen: X.D1 kill `fuser foo.c` X.Sh DIAGNOSTICS X.Ex -std X.Sh SEE ALSO X.Xr fstat 1 , X.Xr ktrace 1 X.Sh STANDARDS XThe X.Nm Xutility is designed to comply with the X.St -p1003.1-2001 Xspecification. X.Sh BUGS XThe user name associated with the process's effective user ID is written Xinstead of that of the real user ID.
