echo1

Usage

Overview

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:

-E

Disable interpretation of backslash escape sequences (default).

-e

Enable interpretation of the following backslash escape sequences:

\\

A literal backslash.

\a

Alert (BEL).

\b

Backspace.

\c

Suppress further output, including the trailing newline character.

\e

Escape character.

\f

Form feed.

\n

Newline.

\r

Carriage return.

\t

Horizontal tab.

\v

Vertical tab.

\0nnn

The character whose octal value is nnn (zero to three octal digits).

\xhh

The character whose hexadecimal value is hh (one or two hexadecimal digits).

-n

Do not print the trailing newline character.

Exit status

The echo utility exits 0 on success, and >0 if an error occurs.
