Consider the following Makefile:

doit: there

cp here down$/$there

cd $$($ cat there $)$ ; ls

here:

pwd $>$ here

there: down here

sed $$s:$/[^/]*$$$::$<$ here $>$ there

down:

mkdir down

$($a$)$ If this Makefile was in an otherwise$-$empty directory named m$1,$ what commands would

be executed, in what order, when the user ran $$make$?$

$($b$)$ Draw the subtree, showing all the files in m$1$ after $$make$$ had finished.
