echo -- display a line of text


echo [STRING]... 


The echo command is as specified in the Single UNIX Specification but with the following differences.

Unlike the behavior specified in the Single UNIX Specification, whether echo supports options is implementation defined. The behavior of echo if any arguments contain backslashes is also implementation defined. Applications must not run echo with a first argument starting with a hyphen, or with any arguments containing backslashes; they must use printf in those cases.
