无法在Bash 4中使用Checkjobs和Autocd

Question

Bash 4中有新选项:checkjobs和autocd.但是,我没有找到他们的文档

man bash

我跑得不成功

{checkjobs,autocd}

我在发行说明中找到了以下内容

 There is a new `checkjobs` option that causes the shell to check for and
 report any running or stopped jobs at exit

和

There is a new `autocd` option that, when enabled, causes bash to attempt
to `cd` to a directory name that is supplied as the first word of a
simple command.

你怎么能使用autocd和checkjobs？

Answer 1

autocd并且checkjobs不是命令,而是它们是选项.

可以使用shopt内置设置它们.

例:

shopt -s autocd

和

shopt -s checkjobs

要么

shopt -s autocd checkjobs

设置两者.
