NAME
lslocks - list local system locks
SYNOPSIS
lslocks [options]
DESCRIPTION
lslocks lists information about all the currently held file locks in a Linux system.
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 fcntl(2) for more details.
OPTIONS
-b, --bytes
By default, the unit, sizes are expressed in, is byte, and unit prefixes are in power of 2^10 (1024). Abbreviations of symbols are exhibited truncated in order to reach a better readability, by exhibiting alone the first letter of them; examples: "1 KiB" and "1 MiB" are respectively exhibited as "1 K" and "1 M", then omitting on purpose the mention "iB", which is part of these abbreviations.
-i, --noinaccessible
-J, --json
-n, --noheadings

The default list of columns may be extended if list is specified in the format +list (e.g., lslocks -o +BLOCKER).
