Most command shells such as bash or cmd.exe support "file globbing", the ability to identify a group of files by using wildcards.

Wildcard matching provides four features:

• Any character represents itself apart from those mentioned below. Thus 'c' matches the character 'c'.
• The '?' character matches any single character.
• The '*' matches zero or more of any characters.
• Sets of characters can be represented in square brackets. Within the character class, like outside, backslash has no special meaning.

For example we could identify HTML files with *.html. This will match zero or more characters followed by a dot followed by 'h', 't', 'm' and 'l'.
