FINCORE(1)                    User Commands                   FINCORE(1)

NAME         top

       fincore - count pages of file contents in core

SYNOPSIS         top

       fincore [options] file...

DESCRIPTION         top

       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         top

       -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.
