Directories
Perl offers more functions that deal with files, I/O, and directory management than any other capability it supports. This wide variety of file functions is supplemented by some of the most terse (does more in fewer words - that's good!) syntax of any language, making file and directory I/O operations extremely easy.

Open/Close	closedir, opendir
Random Access	readdir, rewinddir, seekdir, telldir
Directory Changes	chdir, chroot, mkdir, rmdir

Directory Handling Syntax

Directory Functions Reference
Here's a quick reference of the available directory functions, in alphabetical order.

Unless otherwise noted, these functions operate on $_ by default.

• chdir - change the current working directory

      chdir EXPR
      

• chroot - make directory new root for path lookups

      chroot FILENAME
      

• closedir - close directory handle

      closedir DIRHANDLE
      

• mkdir - create a directory

      mkdir FILENAME, MASK         # mask defaults to 0777
      

• opendir - open a directory

      opendir DIRHANDLE, EXPR
      

• readdir - get a directory from a directory handle

      readdir DIRHANDLE
      

• rewinddir - reset directory handle

      rewinddir DIRHANDLE
      

• rmdir - remove a directory

      rmdir FILENAME
      

• seekdir - reposition directory points

      seekdir DIRHANDLE, POS

      telldir DIRHANDLE
