+.TH LSLOCKS 8 "December 2014" "util-linux" "System Administration"
+.SH NAME
+lslocks \- list local system locks
+.SH SYNOPSIS
+.B lslocks
+[options]
+
+.SH DESCRIPTION
+.B lslocks
+lists information about all the currently held file locks in a Linux system.
+.sp
+Note that lslocks also lists OFD (Open File Description) locks, these locks are
+not associated with any process (PID is -1).  OFD locks are associated with the
+open file description on which they are acquired.  This lock type is available
+since Linux 3.15, see \fBfcntl\fR(2) for more details.
+
+.SH OPTIONS
+.TP
+.BR \-b , " \-\-bytes"
+Print the SIZE column in bytes rather than in a human-readable format.
+.TP
+.BR \-i , " \-\-noinaccessible"
+Ignore lock files which are inaccessible for the current user.
+.TP
+.BR \-J , " \-\-json"
+Use JSON output format.
+.TP
+.BR \-n , " \-\-noheadings"
+Do not print a header line.
+.TP
+.BR \-o , " \-\-output " \fIlist\fP
+Specify which output columns to print.  Use
+.B "--help"
+to get a list of all supported columns.
+
+The default list of columns may be extended if \fIlist\fP is
+specified in the format \fI+list\fP (e.g. \fBlslocks -o +BLOCKER\fP).
+.TP
+.B \-\-output\-all
+Output all available columns.
+.TP
+.BR \-p , " \-\-pid " \fIpid\fP
+Display only the locks held by the process with this \fIpid\fR.
+.TP
+.BR \-r , " \-\-raw"
+Use the raw output format.
+.TP
+.BR \-u , " \-\-notruncate"
+Do not truncate text in columns.
+.TP
+.BR \-V , " \-\-version"
+Display version information and exit.
+.TP
+.BR \-h , " \-\-help"
+Display help text and exit.
+
+.SH OUTPUT
+.IP "COMMAND"
+The command name of the process holding the lock.
+.IP "PID"
+The process ID of the process which holds the lock or -1 for OFDLCK.
+.IP "TYPE"
+The type of lock; can be FLOCK (created with \fBflock\fR(2)), POSIX
+(created with \fBfcntl\fR(2) and \fBlockf\fR(3)) or OFDLCK (created with fcntl(2).
+.IP "SIZE"
+Size of the locked file.
+.IP "MODE"
+The lock's access permissions (read, write).  If the process is blocked and waiting for the lock,
+then the mode is postfixed with an '*' (asterisk).
+.IP "M"
+Whether the lock is mandatory; 0 means no (meaning the lock is only advisory), 1 means yes.
+(See \fBfcntl\fR(2).)
+.IP "START"
+Relative byte offset of the lock.
+.IP "END"
+Ending offset of the lock.
+.IP "PATH"
+Full path of the lock.  If none is found, or there are no permissions to read
+the path, it will fall back to the device's mountpoint and "..." is appended to
+the path.  The path might be truncated; use
+\fB\-\-notruncate\fR to get the full path.
+.IP "BLOCKER"
+The PID of the process which blocks the lock.
+
+.SH NOTES
+.nf
+The \fBlslocks\fR command is meant to replace the \fBlslk\fR(8) command,
+originally written by Victor A. Abell <abe@purdue.edu> and unmaintained
+since 2001.
