Perl support similar pattern matching using wildcard operators like unix (and DOS) shells do; you have to enclose the pattern matching between "<>".
FILE PATTERN MATCHING OPERATORS
| * | match zero or more characters |
| ? | match any single character |
| {expr2,expr2,...exprN} | match expr1 OR expr2 OR ... exprN |
| [...] | match any single character specified within the square brackets |
| [!...] | match any single character except those specified within brackets |
Note:
These wildcard operators are also used on regular expressions but the meaning is different when they are used in regular expressions (for example, "too?" matches "too" and "to" in a regular expression context, in a file pattern matching context it matches "tool" but doesn't match "too" or "to").
Examples:
#-- get all files ending in .pl
@list = <*.pl>;
#-- get all files ending in .c or .h
@list = <*.[ch]>;
#-- files ending in .rpm or .gz
@list = <*.{rpm,gz}>;
#-- files begining with a number
@list = <[0-9]*>;
