=over =item chdir EXPR X X X =item chdir FILEHANDLE =item chdir DIRHANDLE =item chdir Changes the working directory to EXPR, if possible. If EXPR is omitted, changes to the directory specified by C<$env{home}>, if set; if not, changes to the directory specified by C<$env{logdir}>. (Under VMS, the variable C<$env{'sys$login'}> is also checked, and used if it is set.) If neither is set, L|/chdir EXPR> does nothing and fails. It returns true on success, false otherwise. See the example under L|/die LIST>. On systems that support L, you may pass a filehandle or directory handle as the argument. On systems that don't support L, passing handles raises an exception. =back
