|ECHO(1)||General Commands Manual||ECHO(1)|
echoutility writes any specified operands, separated by single blank (‘ ’) characters and followed by a newline (‘\n’) character, to the standard output.
When no operands are given, only the newline is written. The
-- operand, which generally denotes an end to option
processing, is treated as part of string.
The options are as follows:
echoutility exits 0 on success, and >0 if an error occurs.
echoutility is compliant with the IEEE Std 1003.1-2008 (“POSIX.1”) specification.
The flag [
-n] conflicts with the behaviour
mandated by the X/Open System Interfaces option of the IEEE
Std 1003.1-2008 (“POSIX.1”) specification, which says
it should be treated as part of string. Additionally,
echo does not support any of the backslash character
sequences mandated by XSI.
Where portability is paramount, use printf(1).
echoutility appeared in Version 2 AT&T UNIX.
