A simple shell command such as echo a b c consists of the command itself followed by arguments, separated by spaces.

More complex shell commands are composed of simple commands arranged together in a variety of ways: in a pipeline in which the output of one command becomes the input of a second, in a loop or conditional construct, or in some other grouping. • : The most common type of command. • : Connecting the input and output of several commands. • : How to execute commands sequentially. • : Shell commands for control flow. • : Two-way communication between commands. • : Running commands in parallel.
