NAME

6       fincore - count pages of file contents in core
7

SYNOPSIS

9       fincore [options] file...
10

DESCRIPTION

12       fincore counts pages of file contents being resident in memory (in
13       core), and reports the numbers. If an error occurs during counting,
14       then an error message is printed to the stderr and fincore continues
15       processing the rest of files listed in a command line.
16
17       The default output is subject to change. So whenever possible, you
18       should avoid using default outputs in your scripts. Always explicitly
19       define expected columns by using --output columns-list in environments
20       where a stable output is required.
21

OPTIONS

23       -n, --noheadings
24           Do not print a header line in status output.
25
26       -b, --bytes
27           Print the sizes in bytes rather than in a human-readable format.
28
29           By default, the unit, sizes are expressed in, is byte, and unit
30           prefixes are in power of 2^10 (1024). Abbreviations of symbols are
31           exhibited truncated in order to reach a better readability, by
32           exhibiting alone the first letter of them; examples: "1 KiB" and "1
33           MiB" are respectively exhibited as "1 K" and "1 M", then omitting
34           on purpose the mention "iB", which is part of these abbreviations.
35
36       -o, --output list
37           Define output columns. See the --help output to get a list of the
38           currently supported columns. The default list of columns may be
39           extended if list is specified in the format +list.
40
41       -r, --raw
42           Produce output in raw format. All potentially unsafe characters are
43           hex-escaped (\x<code>).
44
45       -J, --json
46           Use JSON output format.
47
48       -h, --help
49           Display help text and exit.
50
51       -V, --version
52           Print version and exit.
