echo – write arguments to the standard output
echo [-n] [string ...]
The echo utility writes any specified operands, separated by single blank
(‘ ’) characters and followed by a newline (‘\n’) character, to the
The following option is available:
-n Do not print the trailing newline character. This may also be
achieved by appending ‘\c’ to the end of the string, as is done by
iBCS2 compatible systems. Note that this 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. Applications aiming for
maximum portability are strongly encouraged to use printf(1) to
suppress the newline character.
Some shells may provide a builtin echo command which is similar or
identical to this utility. Most notably, the builtin echo in sh(1) does
not accept the -n option. Consult the builtin(1) manual page.
The echo utility exits 0 on success, and >0 if an error occurs.
