Bash 4 中有新的选项:checkjobs 和 autocd。但是,我没有找到他们的文档
man bash
我跑不成功
{checkjobs,autocd}
我在发行说明中发现了以下内容
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.
如何使用 autocd 和 checkjobs?
