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.
