NAME
popd - Remove directories from stack.
SYNOPSIS
popd [-n] [+N | -N]
DESCRIPTION
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 Suppresses the normal change of directory when removing
directories from the stack, so only the stack is manipulated.
Arguments:
+N Removes the Nth entry counting from the left of the list
shown by `dirs', starting with zero. For example: `popd +0'
removes the first directory, `popd +1' the second.
-N Removes the Nth entry counting from the right of the list
shown by `dirs', starting with zero. For example: `popd -0'
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.
