FINCORE(1)                        User Commands                       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.
