hi friends,


whats the diffrence between shutdown and halt, poweroff commands??? what is standby mode???



pls reply.
Thanks in advance...

Shutdown -h will change to init level 0 and has other options such as notifying users that the system is going down. I think that running shutdown will end up running halt once run level 0 is reached. One thing the halt command can do is park ide drives which will flush the drives' write buffers. Look in the shutdown and halt manpages for more definitive information. It is better to use the shutdown command instead of halt. As a matter of fact, shutdown checks if you are in init level 0 and if not, it calls the shutdown command.
