echo(1) manual page

The echo utility writes any specified operands, separated by single blank (‘ ’) characters and followed by a newline (‘\n’) character, to the standard output.

The following option is available:

-n

Do not print the trailing newline character.

The end-of-options marker - is not recognized and written literally.

The newline may also be suppressed by appending ‘\c’ to the end of the string, as is done by iBCS2 compatible systems. Note that the -n option as well as the effect of ‘\c’ are implementation-defined in IEEE Std 1003.1-2001 ("POSIX.1") as amended by Cor.amp; 1-2002. For portability, echo should only be used if the first argument does not start with a hyphen (‘-’) and does not contain any backslashes (‘\’). If this is not sufficient, printf(1) should be used.

Most shells provide a builtin echo command which tends to differ from this utility in the treatment of options and backslashes. Consult the builtin(1) manual page.
