echo [-neE] [arg ...]
Prints its arguments (separated by spaces) followed by a newline, to standard out. The newline is suppressed if any of the arguments contain the backslash sequence \c. See print command below for a list of other backslash sequences that are recognized.
The options are provided for compatibility with BSD shell scripts: -n suppresses the trailing newline, -e enables backslash interpretation (a no-op, since this is normally done), and -E which suppresses backslash interpretation.

echo
ECHO(1) BSD 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 ('
') 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 sup-
press 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.
EXIT STATUS
The echo utility exits 0 on success, and >0 if an error occurs.
SEE ALSO builtin(1), csh(1), printf(1), sh(1)STANDARDS
The echo utility conforms to IEEE Std 1003.1-2001 (``POSIX.1'') as amended by Cor. 1-2002.
