Unable to use Checkjobs and Autocd in Bash 4
There are new options in Bash 4: checkjobs and autocd.
However, I did not find documentation for them at
I run unsuccessfully
I found the following in release notes
There is a new `checkjobs` option that causes the shell to check for and report any running or stopped jobs at exit
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.
How can you use autocd and checkjobs?
