|Purpose:||Display a message to standard error (STDERR) without performing any variable expansion or redirection.|
|message||Text to display.|
ECHOXERR will echo the message text to STDERR without doing any of the parser processing (variables, redirection, escaped characters, etc.).
•The first space after the command name is ignored.
•Trailing spaces in message are ignored.
•The ASCII NUL character cannot be included in message.
ECHOXERR is useful for text output when you want to display some text that may have embedded special characters (like %, <. >, or |).
