Understand it like this---
suppose you have to build your application or have to compile a big code that will take plenty of time.
put the commands to compile or build the code,then press ctrl-Z,this will take you to background and the process will stop.
if you put a command --
jobs -l
it will show you the job number of the commands in the background,if there is only one command in the background then put only bg at the command prompt it will start the process in the background.or if there are multiple jobs running then put the job numbers associated with the command which you want to run in background.
Meanwhile you can The window is for you,you can do so many things there.
If you want to take your jobs again running in the main window put fg wioth the job number.Make a try of all this and let me know any doubts.
Thanks
Namish

sulogin
SULOGIN(8) Linux System Administrator's Manual SULOGIN(8)
NAME
sulogin -- Single-user login
SYNOPSIS
sulogin [ -e ] [ -p ] [ -t timeout ] [ tty-device ]
DESCRIPTION
sulogin can be invoked by init(8) when the system goes into single user mode (this is done through an entry in inittab(5)). Init also tries
to execute sulogin when it is passed the -b flag from the bootmonitor (eg, LILO).
The user is prompted
Give root password for system maintenance
(or type Control-D for normal startup):
sulogin will connected to the current terminal, or to the optional device that can be specified on the command line (typically /dev/con-
sole).
If the -p flag was set, the single-user shell will be invoked with a dash as the first character in argv[0]. That will cause most shells to
behave as a login shell. The default is not to do this, so that the shell will not read /etc/profile or $HOME/.profile at startup.
After the user exits the single-user shell, or presses control-d at the prompt, the system will (continue to) boot to the default runlevel.
ENVIRONMENT VARIABLES
sulogin looks for the environment variable SUSHELL or sushell to determine what shell to start. If the environment variable is not set, it
will try to execute root's shell from /etc/passwd. If that fails it will fall back to /bin/sh.
This is very valuable together with the -b flag to init. To boot the system into single user mode, with the root file system mounted
read/write, using a special "failsafe" shell that is statically linked (this example is valid for the LILO bootprompt)
boot: linux -b rw sushell=/sbin/sash
FALLBACK METHODS
sulogin checks the root password using the standard methods first. If the -e option was specified, sulogin examines the next files to find
the root password. If they are damaged, or non-existant, it will use fallback methods that even go so far as to provide you with a shell
prompt without asking for the root password if they are irrepairably damaged.
/etc/passwd,
/etc/shadow (if present)
