echo(1sh5)
Name
echo − echo arguments
Syntax
echo [ arg ] ...
Description
The echo command writes its arguments separated by blanks and terminated by a new-line on the standard output. It also understands C-like escape conventions; however, beware of conflicts with the shell’s use of the backslash (\) character:
\b backspace
\c print line without new-line
\f form-feed
\n new-line
\r carriage return
\t tab
\v vertical tab
\\ backslash
\n the 8-bit character whose ASCII code is the 1-, 2- or 3-digit octal number n, which must start with a zero.
The echo is useful for producing diagnostics in command files and for sending known data into a pipe.
