You can use "cd -" to go back to the previous directory.

  $OLDPWD also holds the previous directory.

  Does that work like a stack or does it just swap?
  • kbp 9y ago
    It only swaps; you can use pushd and popd if you want a stack.

      Also: - "cd -" has no interaction with the pushd/popd stack except in the sense that it alters the top of the stack (the current working dir). It doesn't swap the two top entries of the directory stack, but swaps the top with an off-stack saved location ($OLDPWD). - "pushd" with no arguments swaps the top two stack entries.

  If you use "mkdir -", bash will not change into this directory. Not even if you use "cd -- -". "cd ./-" works.
