Crontab command details
I,Crond Introduction
Crond is a daemon in linux that is used to periodically execute a task or wait for processing some events. It is similar to a scheduled task in windows. After the operating system is installed, by default, the service tool is installed and the crond process is automatically started. The crond Process regularly checks whether there are tasks to be executed every minute. If there are tasks to be executed, the
The previous day learned that the at command is for routine scheduled tasks that run only once, and that the Linux system is controlled by the cron (Crond) system service. Linux systems have a lot of planned work on them, so this system service is started by default. In addition, because the user can set up scheduled tasks themselves, the Linux system also provides a command for the user to control scheduled tasks: the crontab command. I. Crond profil
The Linux system is controlled by a cron (Crond) system service. The Linux system already has a lot of planned work on it, so this system service is started by default. In addition, because the user can set the scheduled task themselves, the Linux system also provides the user Control Scheduling task command: crontab command.

SunOS
SunOSIt was originally called by Sun's operating system because SunBill Joy, one of the founders of Microsystem, is from U. C. Berkeley, so SunOS is mainly based on bsdunix. SunOSAt the beginning of 5.0, sun's operating system development started to switch to System V Release 4, and a new name named Solaris 2.0; SolarisSun deleted "2 in the version number after 2.6. Therefore, SunOS 5.10 is called Solaris
Solaris 10 IP Filter Technology detailed explanation Solaris 10 integrated a lot of open source software, IP Filter is one of them, this software package directly replaces the original SUN screen firewall software package. The IP Filter package completely replaces sun screen, which provides stateful packet filtering and Network Address Translation (NAT). It also provides non-stateful packet filtering and th

Sun officials announced the details of their open-source code policy on July 15, November 2. Sun publicly revealed the long-standing Conjecture of most industry vendors that Sun's top priority is to support its Solaris operating system, not the Linux operating system.
At a meeting prior to the release of Solaris 10, John, Senior Marketing Director of Sun's Network Systems Group, said the cost of
