我正在尝试以下..
系统“cd目录文件夹”
但它失败了，我也尝试系统“退出”离开终端，但它失败了。
Code:
chdir('path/to/dir') or die "$!";
Perldoc:
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 upon success, false otherwise. See the
example under "die".
On systems that support fchdir, you might pass a file handle or directory
handle as argument. On systems that don't support fchdir, passing handles
produces a fatal error at run time.
