This is very useful for managing multiple files sharing similar characteristics such as the same file extension.
''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''', '''more''', '''head''', '''tail''', '''sort''', '''uniq''', '''cut''', '''tr''', and '''wc'''.<br><br>
