kexec [options] files...

\fP and --> \fP escape sequences to invode bold face and italics, --> kexec allows one to load another kernel from the currently running Linux kernel. Normally one would load a kernel, and possibly an initial ramdisk, into the currently running kernel using kexec and then initiate a warm reboot by executing kexec again with appropriate option.

These programs follow the usual GNU command line syntax, with long options starting with two dashes (‘-’). A summary of options is included below.

-h, --help	Show summary of options.
-v, --version
	Show version of program.
-f, --force
	Force an immediate kexec without calling shutdown.
-x, --no-ifdown
	Don’t bring down network interfaces. (if used, must be last option specified)
-l, --load	Load the new kernel into the current kernel.
-p, --load-panic
	Load the new kernel for use on panic.
-u, --unload
	Unload the current kexec target kernel.
-e, --exec	Execute a currently loaded kernel.
-t, --type=TYPE
	Specify the new kernel is of this type.
--> --mem-min=<addr>
	Specify the lowest memory addres to load code into.
--> --mem-max=<addr>
	Specify the highest memory addres to load code into.
There may be additional options supported on individual architectures. Use --help option to see those options.
