NAMEecho — write arguments to the standard output
|echo||[ -n][ string ...]|
DESCRIPTIONThe 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:
- 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. 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.
EXIT STATUSThe echo utility exits 0 on success, and >0 if an error occurs.
STANDARDSThe echo utility conforms to IEEE Std 1003.1-2001 (“POSIX.1”) as amended by Cor. 1-2002.
