Consider the following Makefile

doit: there

cp here down$/$there

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

here:

pwd $>$ here

there: down here

sed $\text{'}$s:$/[-/]*$$$::$\text{'}$ 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
