NAME
echo —
write arguments to the standard
output
SYNOPSIS
echo |
[-n] [string ...] |
DESCRIPTION
Theecho 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. 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. Consult the
builtin(1) manual page.
EXIT STATUS
The echo utility exits 0 on
success, and >0 if an error occurs.
