NAME
lslocks - list local system locks
SYNOPSIS
lslocks [options]
DESCRIPTION
lslocks lists information about all the currently held file locks in a Linux system.
OPTIONS
-h, --help Print a help text and exit. -n, --noheadings Do not print a header line. -o, --output list Specify which output columns to print. Use --help to get a list of all supported columns. The default list of columns may be extended if list is specified in the format +list (e.g. lslocks -o +BLOCKER). -p, --pid pid Display only the locks held by the process with this pid. -r, --raw Use the raw output format. -u, --notruncate Do not truncate text in columns.
OUTPUT
COMMAND The command name of the process holding the lock. PID The process ID of the process which holds the lock. TYPE The type of lock; can be FLOCK (created with flock(2)) or POSIX (created with fcntl(2) and lockf(3)). SIZE Size of the locked file. 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). M Whether the lock is mandatory; 0 means no (meaning the lock is only advisory), 1 means yes. (See fcntl(2)). START Relative byte offset of the lock. END Ending offset of the lock. 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 mount- point. The path might be truncated; use --notruncate to get the full path. BLOCKER The PID of the process which blocks the lock.
NOTES
The lslocks command is meant to replace the lslk(8) command, originally written by Victor A. Abell <abe@purdue.edu> and unmaintained since 2001.
