7.5    Executing Commands

Usually you start commands simply by entering the command name. In addition to that, there are some options to execute multiple commands in a row (see Table 7.4).

Command	Function
cmd1; cmd2	Executes the commands one after the other
cmd1 && cmd2	Executes command 2 if command 1 was successful
cmd1 || cmd2	Executes command 2 if command 1 returns an error
cmd &	Starts the command in the background
cmd1 & cmd2	Starts command 1 in the background, command 2 in the foreground
(cmd1 ; cmd2)	Executes both commands in the same shell
