When you type <B>halt</B> the OS terminates all processes and prepares the system to shutdown the power. Normally, halt is used before a power shutdown (to add a disk, card, etc.) for any reason.

Normally, if you want to reboot and get the lilo prompt, the command is <B>shutdown -r now</B>, where "r" means reboot and "now" means now Smilie (you could say to shutdown and reboot in 5 minutes, etc., BTW, etc.)

Also, just a word of caution, before typing these commands, it is good to do a <B>sync</B> twice or so. This flushes certain information in RAM to disk, very helpful before shutdown or reboot. Most systems do this as a part of the shutdown scripts, but it is considered good practice to do this from the command line anyway. You will develop a good habit over time of typing sync;sync Smilie

SHUTDOWN(8)							     shutdown							       SHUTDOWN(8)

NAME
shutdown - Halt, power-off or reboot the machine SYNOPSIS
shutdown [OPTIONS...] [TIME] [WALL...] DESCRIPTION
shutdown may be used to halt, power-off or reboot the machine. The first argument may be a time string (which is usually "now"). Optionally, this may be followed by a wall message to be sent to all logged-in users before going down. The time string may either be in the format "hh:mm" for hour/minutes specifying the time to execute the shutdown at, specified in 24h clock format. Alternatively it may be in the syntax "+m" referring to the specified number of minutes m from now. "now" is an alias for "+0", i.e. for triggering an immediate shutdown. If no time argument is specified, "+1" is implied. Note that to specify a wall message you must specify a time argument, too. If the time argument is used, 5 minutes before the system goes down the /run/nologin file is created to ensure that further logins shall not be allowed. OPTIONS
The following options are understood: --help Prints a short help text and exits. -H, --halt Halt the machine. -P, --poweroff Power-off the machine (the default). -r, --reboot Reboot the machine. -h Equivalent to --poweroff, unless --halt is specified. -k Do not halt, power-off, reboot, just write wall message. --no-wall Do not send wall message before halt, power-off, reboot. -c Cancel a pending shutdown. This may be used cancel the effect of an invocation of shutdown with a time argument that is not "+0" or "now". EXIT STATUS
On success, 0 is returned, a non-zero failure code otherwise. SEE ALSO
