When using popd, how to push the current directory onto the stack?

1
$ pwd; pushd /tmp; pwd; popd; pwd
/home/users/foo
/tmp ~
/tmp
~
/home/users/foo

Bash will keep a history of the directories you visit, you just have to ask. Bash stores the history in a stack and uses the commands pushd and popd to manage the stack.

If you don't need multiple levels of directory history, you can also do:

cd foo
# do your stuff in foo
cd -

Compared to pushd/popd, this has the disadvantage that if cd foo fails, you end up in the wrong directory with cd -.

(Probably cd - is more handy outside scripts. "Let's go back where I just was.")

See Use pushd and popd to manipulate directory stack for more help.

    I also advise the OP to google around for the concept of stack, and the push and pop operations in programming languages. – Rui F Ribeiro Jun 24 '16 at 8:03

It should be just

[$]> pushd .

no?

pushd -n $(pwd)

adds the current directory $(pwd) to the stack without changing directory.

From help pushd in bash:

Options:

-n Suppresses the normal change of directory when adding directories to the stack, so only the stack is manipulated.
