The Operating system is my company's own OS. The output of "free" is like
"
MemTotal: XXXXX KB
MemFree: XXXXX KB
Buffer: XXX KB
"
I already know how to deal with the "ps" command, but my issue is getting the MemFree from the free command and creating an if statement based off the MemFree without having the do something like
"
free > Memory.txt
grep MemFree Memory.txt
if ( #some command that checks MemFree, and if MemFree is less then or equal to 1000 KB)
then
ps > psLog.txt #i know this part works just fine
else

get_phys_pages
GET_PHYS_PAGES(3) Linux Programmer's Manual GET_PHYS_PAGES(3)
NAME
get_phys_pages, get_avphys_pages - get total and available physical page counts
SYNOPSIS
#include <sys/sysinfo.h>
long int get_phys_pages(void);
long int get_avphys_pages(void);
DESCRIPTION
The function get_phys_pages() returns the total number of physical pages of memory available on the system.
The function get_avphys_pages() returns the number of currently available physical pages of memory on the system.
RETURN VALUE
On success, these functions return a nonnegative value as given in DESCRIPTION. On failure, they return -1 and set errno to indicate the
cause of the error.
ERRORS
ENOSYS The system could not provide the required information (possibly because the /proc filesystem was not mounted).
CONFORMING TO
These functions are GNU extensions.
NOTES
These functions obtain the required information by scanning the MemTotal and MemFree fields of /proc/meminfo.
The following sysconf(3) calls provide a portable means of obtaining the same information as the functions described on this page.
total_pages = sysconf(_SC_PHYS_PAGES); /* total pages */
avl_pages = sysconf(_SC_AVPHYS_PAGES); /* available pages */
EXAMPLE
The following example shows how get_phys_pages() and get_avphys_pages() can be used.
#include <stdio.h>
#include <stdlib.h>
#include <sys/sysinfo.h>
int
main(int argc, char *argv[])
{
printf("This system has %ld pages of physical memory and "
"%ld pages of physical memory available.
",
get_phys_pages(), get_avphys_pages());
exit(EXIT_SUCCESS);
}

COLOPHON
This page is part of release 4.15 of the Linux man-pages project. A description of the project, information about reporting bugs, and the
