pushd

pushd will push a directory onto the directory stack.   With

<no arguments>, exchange the top two elements.

<+n> Rotate the n'th entry to the top of the stack and cd to
     it.
     *M*: The 2nd entry is (the first) +1.
     *U*: Use it to change dir back and forth

<dir> Push the current working directory onto the  stack and
     change to dir.

dirs dirs will print the directory stack, most recent to the left; the first directory shown is the current directory. Constantly changing. *U*: Use pushd whenever you want to keep current dir in stack

popd +n Discard the n'th entry in the stack. *U*: Use it only if you want to discard something, which un- likly to happen.
