|-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 -p1003.1-2001 as amended by Cor. 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.
The echo utility conforms to -p1003.1-2001 as amended by Cor. 1-2002.
