推荐答案

下载Coreutils(它是包含所有这些命令的软件包):

Download Coreutils (it's the package which contains all of these commands): http://ftp.gnu.org/gnu/coreutils/coreutils-8.9.tar.gz.

将其打开，并找到每个源代码.我认为tarball组织得很好.

Rip it open, and find the source code for each one. I think the tarball is organized quite nicely.

以及其他语言的一些命令实现(我喜欢Python，因为它可读):

And some implementations of the commands in other languages (I like Python, as it's readable):

1. ls: http://www.pixelbeat.org/talks/python/ls.py.html .
2. cat: http://www.unix.com/302420159-post2.html .
3. top是复杂的.祝你实施顺利！
