9 fincore [options] file...
10
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
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
