 | |

 | |
|  *  interpreting relative pathnames instead of the current working directory.
 | |
|  *  As the results are not prefixed with the base directory name in this
 | |
|  *  case, you will need to prepend the base directory name if you want real
 | |
|  *  paths.
 | |

 | |
|  *  Note that the pattern is not a regexp, it's closer to a shell glob.
 | |

 | |

 | |
|  *  <code>*</code>::
 | |
|  *    Matches any file. Can be restricted by other values in the glob.
 | |
|  *    Equivalent to <code>/ .* /mx</code> in regexp.
 | |
|  *
 | |
|  *    <code>*</code>::     Matches all files
 | |
|  *    <code>c*</code>::    Matches all files beginning with <code>c</code>
 | |
|  *    <code>*c</code>::    Matches all files ending with <code>c</code>
 | |
|  *    <code>\*c\*</code>:: Match all files that have <code>c</code> in them
 | |
|  *                         (including at the beginning or end).
 | |
|  *
 | |
|  *    Note, this will not match Unix-like hidden files (dotfiles).  In order
 | |
|  *    to include those in the match results, you must use the
 | |
|  *    File::FNM_DOTMATCH flag or something like <code>"{*,.*}"</code>.
 | |
|  *
 | |
|  *  <code>**</code>::
 | |
|  *    Matches directories recursively.
 | |
|  *
 | |
|  *  <code>?</code>::
 | |
|  *    Matches any one character. Equivalent to <code>/.{1}/</code> in regexp.
 | |
|  *
 | |
|  *  <code>[set]</code>::
 | |
|  *    Matches any one character in +set+.  Behaves exactly like character sets
 | |
|  *    in Regexp, including set negation (<code>[^a-z]</code>).
 | |
|  *
 | |
|  *  <code>{p,q}</code>::
 | |
|  *    Matches either literal <code>p</code> or literal <code>q</code>.
 | |
|  *    Equivalent to pattern alternation in regexp.
 | |
|  *
 | |
|  *    Matching literals may be more than one character in length.  More than
 | |
|  *    two literals may be specified.
 | |
|  *
 | |
|  *  <code> \\ </code>::
 | |
|  *    Escapes the next metacharacter.
 | |
|  *
 | |
|  *    Note that this means you cannot use backslash on windows as part of a
 | |
|  *    glob, i.e.  <code>Dir["c:\\foo*"]</code> will not work, use
 | |
|  *    <code>Dir["c:/foo*"]</code> instead.

|  *  <code>**</code>::
 | |
|  *    Matches directories recursively or files expansively.
 | |
|  *
 | |
|  *  <code>?</code>::
 | |
|  *    Matches any one character. Equivalent to <code>/.{1}/</code> in regexp.

|  *  <code>[set]</code>::

 | |
|  *
 | |
|  *  <code> \ </code>::
 | |
|  *    Escapes the next metacharacter.
 | |
|  *
 | |
|  *  <code>{a,b}</code>::
