Wildcard Masks
Wildcard mask is a string that contains special characters
for pattern matching, whereby:
A question mark (?) can represent a single character;
An asterisk (*) represents any sequence of characters (including
zero character);
A string in brackets ( [string] ) matches exactly one character
that is a member of the character set defined by the string. The string
may contain ranges, which consist of two characters with a dash between
them. You can negate a character set by placing a {!} or a {^} immediately
after the opening bracket.
Below are some examples of wildcard masks:
- html - file names ending with .html (HTML files)
- exe - file names ending with .exe (applications)
a???.html - file names begin with 'a', followed by any three characters
and ".html"
a[A-Z]ch.zip - the second character of the file name is an uppercase letter
[!0-9]any.mp3 - the first character of the file name is NOT a number
