If you are not the administrative user, nothing will happen. For some systems, a priviledged user can issue this command or 'telinit' or some variant of that to place the system runlevel in what is known as "single user" state.
This state is commonly used for maintenance or diagnostic purposes and does not allow multiple users or certain background services to execute.
BG is a command on Unix and Unix-like operating systems to run a job(process) asynchronously in the background.
For Unix, any command is run as a sub-process. You don't need an actual command to create the subprocess. You can also force the process to run in the background by appending a '&' symbol at the end of the command.
A Unix shell can be obtained in Cygwin, a Unix compatibility layer used to compile Unix programs and run them on Windows. Microsoft also makes a shell known as "Windows PowerShell" which incorporates more Unix-like features than the standard command prompt.
su substitute user.. and su is a unix command used to run the shell of another user without logging off..
You need a compiler. Gcc or g++ can be run from a unix shell, or a windows implementation of one like cygwin.
You can use the 'at' command to schedule a job to run in the future (once), or use the 'crontab' command to schedule jobs to run periodically on a time and date basis. Look at the 'man' commands to see how the actual scheduling parameters are specified.
The IPCONFIG command has been run and terminated successfully
The 'uptime' command will tell you exactly how many users are on the system. There are other variations of this, including counting the number of words from the 'users' command, etc., but this is the easiest.
xv6 is not a command prompt itself; rather, it is a simple Unix-like operating system used for educational purposes. It provides a command-line interface where users can execute commands similar to those in Unix. The command prompt in xv6 allows users to interact with the system, run programs, and manage files, but xv6 as a whole encompasses the entire operating system, not just the command prompt.
Unix can be run on a variety of server, mainframe, and workstation devices.
The most graceful way is to use the command: init s If you want to shut everything down before going to single user mode then do init 0 first and from the ok prompt do a boot -s.
