The Magic of strace
Small, somewhat nit-picky critique: the man pages for system calls are in section 2. If you want to see the docs for the "read()" syscall, and not the bash builtin "read", saying "man read" w̶o̶n̶'̶t̶ may not (see follow-up) do what you expect. Instead, you should say<p><pre><code>  man 2 read
</code></pre>
This should probably be mentioned somewhere.<p>Otherwise, great writeup. Thanks for sharing!<p>(edited)
