echo [ -neE ] [ arg ... ]
Write each arg on the standard output, with a space separating
each one. If the -n flag is not present, print a newline at the
end. echo recognizes the following escape sequences:
\a bell character
\b backspace
\c suppress subsequent characters and final newline
\e escape
\f form feed
\n linefeed (newline)
\r carriage return
\t horizontal tab
\v vertical tab
\\ backslash
\0NNN character code in octal
\xNN character code in hexadecimal
\uNNNN unicode character code in hexadecimal
\UNNNNNNNN
unicode character code in hexadecimal
The -E flag, or the BSD_ECHO option, can be used to disable these
escape sequences. In the latter case, -e flag can be used to
enable them.
Note that for standards compliance a double dash does not
terminate option processing; instead, it is printed directly.
However, a single dash does terminate option processing, so the
first dash, possibly following options, is not printed, but
everything following it is printed as an argument. The single
dash behaviour is different from other shells. For a more
portable way of printing text, see printf, and for a more
controllable way of printing text within zsh, see print.
