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.
OPTIONS¶
- -V, --version
