- chdir EXPR

- chdir FILEHANDLE
- chdir DIRHANDLE
- chdir

  Changes the working directory to EXPR, if possible. If EXPR is omitted, changes to the directory specified by `$ENV{HOME}` , if set; if not, changes to the directory specified by `$ENV{LOGDIR}` . (Under VMS, the variable `$ENV{SYS$LOGIN}` is also checked, and used if it is set.) If neither is set, `chdir` does nothing. It returns true on success, false otherwise. See the example under `die`.

  On systems that support fchdir(2), you may pass a filehandle or directory handle as argument. On systems that don't support fchdir(2), passing handles raises an exception.
