what xcatly is the difference between shutting down one's system and halting it..when we use the command poweroff,it says halting system.then how do we shut it down

it's the same thing, just depends how you call the halt program. if you call it by "poweroff" it turns the power off, if you call it by "reboot"... well.. that's obvious.

Code:

trevor chris # ls -l /sbin/poweroff 
   0 lrwxrwxrwx    1 root     root            4 May 11 12:27 /sbin/poweroff -> halt
trevor chris # ls -l /sbin/shutdown 
 16K -rwxr-xr-x    1 root     root          15K May 11 12:27 /sbin/shutdown
trevor chris # ls -l /sbin/reboot   
   0 lrwxrwxrwx    1 root     root            4 May 11 12:27 /sbin/reboot -> halt
trevor chris # ls -l /sbin/halt   
 12K -rwxr-xr-x    1 root     root         8.7K May 11 12:27 /sbin/halt

halt (which IS poweroff or reboot) calls shutdown, which then acts accordingly. the manpage expains these relationships in greater depth
