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 SIZE column in bytes rather than in a human- readable format. -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. -V, --version Display version information and exit. -h, --help Display help text and exit.
