.TH FINCORE 1 "March 2017" "util-linux" "User Commands"
.SH NAME
fincore \- count pages of file contents in core
.SH SYNOPSIS
.B fincore
[options]
.I file ...
.SH DESCRIPTION
.B 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
.B 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
.B \-\-output
.I columns-list
in environments where a stable output is required.
