NAME
fincore - count pages of file contents in core
SYNOPSIS
fincore [options] file...
DESCRIPTION
fincore counts pages of file contents being resident in memory (in
core), and reports the numbers. If an error occurs during counting,
then an error message is printed to the stderr and fincore continues
processing the rest of files listed in a command line.
The default output is subject to change. So whenever possible, you
should avoid using default outputs in your scripts. Always explicitly
define expected columns by using --output columns-list in environments
where a stable output is required.
OPTIONS
-n, --noheadings
Do not print a header line in status output.
-b, --bytes
Print the sizes in bytes rather than in a human-readable format.
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.
-o, --output list
Define output columns. See the --help output to get a list of the
currently supported columns. The default list of columns may be
extended if list is specified in the format +list.
-r, --raw
Produce output in raw format. All potentially unsafe characters are
hex-escaped (\x<code>).
-J, --json
Use JSON output format.
-h, --help
Display help text and exit.
-V, --version
Print version and exit.
