FINCORE(1) User Commands FINCORE(1)
fincore - count pages of file contents in core
fincore [options] file...
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.
-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.
--output-all
Output all available columns.
-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.
