git "borrowed" this idea too. You can use `git checkout -` to checkout the last thing you checked out; very handy when merging.

- nosignal 15y agoPython sort of did too, you can use _ to access the last-returned variable in the interpreter. [testfunc(x) for x in testlist] <successful result> success = _ print _ <successful result> It's useful when using the interpreter as a calculator, or when you're bashing out some calculation you can never remember how to do properly.
- brettnak 15y agoThe same thing also works in irb. >> "foo" => "foo" >> bar = _ => "foo" >> bar => "foo"
- LiveTheDream 15y agoin bash you can use $_ to access the last argument of the previous command. It lets you do things like this: $ pwd /home/foo $ mkdir -p bar/baz/qux && cd $_ $ pwd /home/foo/bar/baz/qux
