→Regular Expressions vs. Filename Expansion
Filename Expansion symbols are used to search, edit and manipulate text and are used with Linux file management commands such as '''ls''', '''rm''', '''mv''', '''cp''', '''cat''', '''less''' and '''more'''. This can represent text contained in files or text as a result of issuing Linux commands using a pipeline.
A '''regular expression''' is a combination of two types of characters: '''literals''' and '''special characters'''.<br>In combination, these characters define a logical pattern. Strings of text can be compared to this pattern <br>to see if they fit the pattern defined by the expression.
