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.
