The following should count directory entries immediately within a given directory, excluding "." and ".." if present (not all filesystems list those explicitly, although they still otherwise work as expected). If compiled with -DTEST, it also provides a main() function to exercise the file counting function. It compiles without warnings and appears to work as expected on at least OS X 10.11.6 (El Capitan), Ubuntu 16.04.2 LTS (Xenial Xerus), and Solaris 9. I checked man pages for various functions and include files rather than going from memory, to be reasonably sure I was doing everything the proper way, so that it would be as portable as possible. The actual function is int countfiles(const char *dirpath), and returns the number of files, or -1 in event of error (with errno reflecting the error that caused it to fail, whether opening the directory, or occasionally some problem reading the directory). There's probably a thing or two I could have done better (a static const int for -1 rather than two uses of the actual constant might have saved four bytes), but other than that, it's pretty clean, IMO.

#include <stdlib.h> #include <errno.h> #include <dirent.h> #include <string.h>

#ifdef TEST extern int countfiles(const char *); #include <stdio.h> int main(int argc, char **argv) { int arg, count, rc = 0;

for (arg = 1; arg < argc; ++arg) {
	if ((count = countfiles(argv[arg])) == -1) {
		perror(argv[arg]);
		rc = 1;
	}
	else
		(void) printf("%s: %d\n", argv[arg], count);
}
return (rc);

} #endif

int countfiles(const char *dirpath) { int count = 0, errno_save; DIR *dirp; struct dirent *dp;

if ((dirp = opendir(dirpath)) == NULL)
	return (-1);

errno = 0; /* because readdir() returns NULL on both EOF and error */

while ((dp = readdir(dirp)) !=NULL) {
	if (strcmp(dp->d_name, ".") == 0 ||
	    strcmp(dp->d_name, "..") == 0)
		continue;
	++count;
}
if (errno != 0) {
	errno_save = errno;
	(void) closedir(dirp);
	errno = errno_save;
	return (-1);
}

(void) closedir(dirp);
return (count);

}

Thanks for the offer, Kenneth. I have a simple script (ls $dir | wc -l) as well but I had thought that it was already a part of the Xymon base. It would be nice to have it as an option to DIR and if I can find the time, I may look into dusting off my C skills and take a stab at it...though using the terms "skills" along side "C" is a stretch for me :-).

Hi Galen, I’m using the count file feature but with a external script on windows along with bbwin 0.13 or 0.12

It a two part script, one cfg file in the bbwin etc folder and one vbs in the bbwin ext folder. Then call it from bbwin.cfg Actually it’s the bbwin, fsmon.vbs that I have altered so it fits my needs.

Let me know if you want the script.

Apparently, I wasn't the only one with this need. I found a thread from 2011. I really don't want to go that route so consider this a feature request that DIR can support more than just size but file count as well.

I could've sworn that Xymon had a way to count the number of files in a particular directory (natively) and you could set up alerts based on number of files. Apparently, I was wrong or I'm not seeing it in the docs. Obviously, I could get clever with file ages but that's just annoying. Am I missing something?

thanks
