Remove directories from stack.
Removes entries from the directory stack. With no arguments, removes
the top directory from the stack, and changes to the new top directory.
Options:
-n
[tab]Suppresses the normal change of directory when removing
[tab]directories from the stack, so only the stack is manipulated.
Arguments:
+N
[tab]Removes the Nth entry counting from the left of the list
[tab]shown by `dirs', starting with zero. For example: `popd +0'
[tab]removes the first directory, `popd +1' the second.
-N
[tab]Removes the Nth entry counting from the right of the list
[tab]shown by `dirs', starting with zero. For example: `popd -0'
[tab]removes the last directory, `popd -1' the next to last.
The `dirs' builtin displays the directory stack.
Exit Status:
Returns success unless an invalid argument is supplied or the directory
change fails.
