Syntax popd [+N | -N] [-n] Key +N Remove the Nth directory (counting from the left of the list printed by dirs), starting with zero. -N Remove the Nth directory (counting from the right of the list printed by dirs), starting with zero. -n Suppress the normal change of directory when removing directories from the stack, so that only the stack is manipulated.
Without arguments, pops the directory stack and returns to the new top directory. The elements are numbered from 0 starting at the first directory listed with dirs; i.e., popd is equivalent to popd +0.
all forms of popd print the final directory stack
popd is a bash builtin command.
