# Square Bracket Wildcards in Shell/Bash
|
|
|
|
Square brackets `[]` in shell wildcards define a character class, matching any single character _within_ the brackets. This allows you to specify a range or set of characters to match in a filename or string. For example, `[abc]` will match either 'a', 'b', or 'c'. You can also use ranges like `[a-z]` to match any lowercase letter or `[0-9]` to match any digit. A caret `^` inside the brackets negates the character class, matching any character _not_ listed (e.g., `[^0-9]` matches anything that isn't a digit).
