ECHO(1) FreeBSD General Commands Manual ECHO(1)
NAME
echo - write arguments to the standard output
SYNOPSIS
echo [-n] [string ...]
DESCRIPTION
The echo utility 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:
-n Do not print the trailing newline character.
EXIT STATUS
The echo utility exits 0 on success, and >0 if an error occurs.
SEE ALSO
csh(1), ksh(1), printf(1)
STANDARDS
The echo utility 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.
echo also exists as a built-in to csh(1) and ksh(1), though with a
different syntax.
Where portability is paramount, use printf(1).
HISTORY
An echo utility appeared in Version 2 AT&T UNIX.
