- Print a text message. Note: quotes are optional:
echo ["Hello World"]

- Print a message with environment variables:
echo ["My path is $PATH"]

- Print a message without the trailing newline:
echo -n ["Hello World"]

- Enable interpretation of backslash escapes (special characters):
echo -e ["Column 1\tColumn 2"]

echo [,SHORT-OPTION/]... [,STRING/]... echo ,LONG-OPTION/

Echo the STRING(s) to standard output.

If -e is in effect, the following sequences are recognized:

\\

\a

\b

\c

\e

\f

NOTE: your shell may have its own version of echo, which usually supersedes the version described here. Please refer to your shell's documentation for details about the options it supports.
