ECHO(1) | General Commands Manual | ECHO(1) |
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
standard output.
The following option is available:
-n
\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.
The echo
utility conforms to
IEEE Std 1003.1-2001 (“POSIX.1”) as
amended by Cor. 1-2002.
