[cs631apue] midterm snapshot feedback

[Jan Schaumann]

Hello,

I'll be returning some feedback on your midterm
snapshot to you in a little bit.  A few things that
are worth calling out to all:

I expect your Makefile to be efficient and compile
source files individually as needed.  That is, no

cc *.c


Use strmode(3) instead of implementing its
functionality yourself.

Use getopt(3) instead of trying to parse command-line
options yourself.

Use humanize_number(3) to, well, humanize a number.

Use isprint(3) instead of checking char integer
values.

Remember to support whiteout files for file suffixes.

I very strongly recommend against using
opendir(3)/readdir(3) -- use fts(3) instead!

I very strongly advise against looking at other
implementations of ls(1).  Even if you don't intend
to, you will likely end up copying code.  (See also:
"clean-room design".)


And remember to run your command against the test
directory and other non-standard scenarios.


Good luck!
