There are new options in Bash 4: checkjobs and autocd. However, I did not find documentation for them at
man bash
I run unsuccessfully
{checkjobs,autocd}
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
and
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?
autocd
and checkjobs
are not commands, but rather, they are options.
They can be set by using the shopt
built-in.
Example:
shopt -s autocd
and
shopt -s checkjobs
or
shopt -s autocd checkjobs
to set both.
