$(10$ points$)$ Consider the following Makefile:

doit: there

cp here down$/$there

cd $ $($ cat there$)$ ; $1$ s

here:

pwd $>$ here

there: down here

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 $m1$ after 'make' had finished.
