FINCORE(1)

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 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.
