Disable Partial All Cron in WHM Cpanel Server Except Root
Disable Partial All Cron in WHM Cpanel Server Except Root
Cronjobs is somewhat a massive activity and could affect the overall server performance. And so, as administrator, we need to disable some users cronjobs to relieve the server load. There is a tricky but simple way to disable partial cronjob in WHM/Cpanel based server. Here are the very simple steps :
1. Create a directory /var/spool/cron.disabled
# mkdir /var/spool/cron.disabled
2. Move the cronjobs you want to be disabled
# mv /var/spool/cron/username /var/spool/cron.disabled
3. Restart http/apache server to take effect
# /etc/init.d/httpd restart

Different Format specifiers available in C except for usual one
Different Format specifiers available in C except for usual one
Guyz I assume that most of the format specifiers of C which are frequently used are known by everyone of us e.g %d for int , %f for float , %c for char , %s for string , %ld for longint ,%lf for double etc so guyz here I am to talk about some other format specifier which are not usually seen in books or not taught in normal classes. so here is the list try to use them in C program, and let me know
| %i | To print integer same as %d |
| %u | To print unsigned integers |
| %x | To print integer value in hexadecimal format |
| %o | To print integer value in octal format |
| %p | Same as %x but used to print value of pointer( memory addresses) |
| %hd | For short integer |
| %lu | For long unsigned |
| %e and %g | To printf float. |
#include<stdio.h>
int main()
{
float f= 3.43;
int i = 16;
printf( " %e " , f);
printf( " %g " , f);
printf( " %x " , i);
printf( " %o " , i);
}
on Gcc output is:
3.430000e+00
3.43
