How do you protect a single meta-character from shell interpretation?

To ignore the special meaning of a meta-character, use the escape character (back-slash) in front of it.
For example, echo $USER would cause the shell variable $USER to be substituted. But if you wanted to actually echo $USER, then use 'echo \$USER'

He shell standard variables are called metacharacters?
Shell metacharacters are special characters that have meaning in a Unix shell. For example, the '$' character followed by letters indicates that the shell variable with that name should have its value substituted. str=hello echo $str will echo out 'hello'. Other metacharacters include the semi-colon (for multiple commands on the same line), the backslash character for escaping special meanings, the single and double quote for combining fields, these are all metacharacters. A metacharacter changes the interpretation of things in various ways.
