NAME

6       lsfd - list file descriptors
7

SYNOPSIS

9       lsfd [option]
10

DESCRIPTION

12       lsfd is intended to be a modern replacement for lsof(8) on Linux
13       systems. Unlike lsof, lsfd is specialized to Linux kernel; it supports
14       Linux specific features like namespaces with simpler code. lsfd is not
15       a drop-in replacement for lsof; they are different in the command line
16       interface and output formats.
17
18       The default output is subject to change. So whenever possible, you
19       should avoid using default outputs in your scripts. Always explicitly
20       define expected columns by using --output columns-list in environments
21       where a stable output is required.
22
23       lsfd uses Libsmartcols for output formatting and filtering. See the
24       description of --output option for customizing the output format, and
25       --filter option for filtering. Use lsfd --help to get a list of all
26       available columns.

OPTIONS

29       -l, --threads
30           List in threads level.
31
32       -J, --json
33           Use JSON output format.
34
35       -n, --noheadings
36           Don’t print headings.
37
38       -o, --output list
39           Specify which output columns to print. See the OUTPUT COLUMNS
40           section for details of available columns.
41
42           The default list of columns may be extended if list is specified in
43           the format +list (e.g., lsfd -o +DELETED).
44
45       -r, --raw
46           Use raw output format.
47
48       --notruncate
49           Don’t truncate text in columns.
50
51       -p, --pid pids
52           Collect information only for specified processes. pids is a list of
53           pids. A comma or whitespaces can be used as separators. You can use
54           this option with pidof(1). See FILTER EXAMPLES.
55
56           Both -Q option with an expression including PID, e.g. -Q (PID ==
57           1), and -p option, e.g. -p 1, may print the same output but using
58           -p option is much more efficient because -p option works at a much
59           earlier stage of processing than the -Q option.
60
61       -i[4|6], --inet[=4|6]
62           List only IPv4 sockets and/or IPv6 sockets.
63
64       -Q, --filter expr
65           Print only the files matching the condition represented by the
66           expr. See also FILTER EXAMPLES.
67
68       -C, --counter label:filter_expr
69           Define a custom counter used in --summary output. lsfd makes a
70           counter named label. During collect information, lsfd counts files
71           matching filter_expr, and stores the counted number to the counter
72           named label. lsfd applies filters defined with --filter options
73           before counting; files excluded by the filters
