Happy Birthday Linux :)

The Linux kernel was originally created by Linus Torvalds, a Finnish computer science student, and first announced to the world on August 25, 1991-exactly 20 years ago today. At the time, Torvalds described his work as a "hobby" and contended that it would not be "big and professional" like the GNU project.

But the Linux kernel turned out to be one of the most significant pieces of open source software ever developed. Over the past two decades, it has grown from a humble hobby project into a global phenomenon that runs on everything from low-cost e-book readers to a majority of the world's supercomputers. Here's how it grew

CTRLALTDEL(8)						     Linux Programmer's Manual						     CTRLALTDEL(8)

NAME

       ctrlaltdel - set the function of the Ctrl-Alt-Del combination

SYNOPSIS

       ctrlaltdel hard|soft

DESCRIPTION

       Based  on examination of the linux/kernel/sys.c code, it is clear that there are two supported functions that the Ctrl-Alt-Del sequence can
       perform: a hard reset, which immediately reboots the computer without calling sync(2) and without any other preparation; and a soft  reset,
       which sends the SIGINT (interrupt) signal to the init process (this is always the process with PID 1).  If this option is used, the init(8)
       program must support this feature.  Since there are now several init(8) programs in the Linux community, please consult	the  documentation
       for the version that you are currently using.

       ctrlaltdel is usually used in the /etc/rc.local file.

FILES
