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.
