Write a simple version of the find program for xv$6$: find all the files in a directory

tree whose name matches a string.

Some hints:

$$ Look at ls$.$c to see how to read directories.

$$ Don$$t try to find any files in the $.$ and $..$ directories.

$3|$ P a g e

$$ Changes to the file system persist across runs of QEMU; to get a clean file

system run make qemu.

Your solution is correct if produces the following output $($when the file system

contains a file a$/$b$)$:

$ make qemu

$...$

init: starting sh

$ echo $>$ b

$ mkdir a

$ echo $>$ a$/$b

$ find $.$ b

$./$b

$./$a$/$b
