accessing array elements ...

	#include <stdio.h>

	/* demonstrate pass by reference of an array of integers*/

Modify arrays inside functions in C. This subject is always tricky and I tend to forget, so here is a not to self.

	#include <stdio.h>
	#include <stdlib.h>
	#include <unistd.h>
	#include <string.h>

	/* demonstrate pass by reference of an array of integers*/
	void resize( int **p, int size ) {
	free( *p );
	p = (int) malloc( size * sizeof(int) );
	int tocpy[]= {8};

oz123 / Cronjob_and_Explanation

Created December 2, 2014 15:55

I was ask to collect all logs from different host to a central place. I was also asked to implement this with rsync. So here is what I came up with:

	cronjob:
	========

	* 1 * * * rsync -e 'ssh -v -i .ssh/log_coll_id_rsa logcol@server' -aP /var/log/mongodb/*.s server:.

	### There results:
	On the server called server you will see in the home directory of the ssh user you created a directory with the log files for each host
	you installed the ssh key, the script and the cron job.

	ls ~
