.SH "BESKRIVNING"
.sp
\fBfincore\fP 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 \fBfincore\fP continues processing the rest of files listed in a command line. \fBfincore\fP uses the \fBcachestat\fP(2) syscall to count resident pages. If the \fBcachestat\fP(2) syscall is not available and \fBcachestat\fP usage is not forced with the \fB\-\-cachestat\fP option, then \fBfincore\fP uses the \fBmincore\fP(2) syscall as a fallback. The \fBcachestat\fP(2) syscall is more efficient than \fBmincore\fP because it does not require a page table lock to walks page tables, and also reports more information than \fBmincore\fP, like the number of cached pages, dirty pages, pages marked for writeback, evicted pages, and recently evicted pages. Another difference between the two syscalls is that if write permissions are not granted to the file, then \fBcachestat\fP(2) returns an error, while \fBmincore\fP(2) for security reasons, returns fake data as if all pages were resident in memory (c.f.r. \c

Standardutdata kan komma att ändras. Så när det är möjligt bör du undvika att använda standardutdata i dina skript. Definiera alltid uttryckligen förväntade kolumner genom att använda \fB\-\-output\fP \fIcolumns\-list\fP i miljöer där en stabil utdata krävs.
