Don't forget it's userspace equiv (strace is syscalls), ltrace. This tracks all lib calls made by process. Under windows, strace is an SSL/TLS monitoring tool (also hella useful). It shows payloads passed to CryptoAPI/CNG libs so you can easily troubleshoot explicitly encrypted protocols like ldaps. Especially useful if you use client authenticated TLS where is is not possible to use a TLS mitm proxy to snoop the lay…
You can use Process monitor http://technet.microsoft.com/en-us/sysinternals/bb896645.asp... to see a similar overview of low level activity. You won't see all the system calls, you can't pipe the output directly, but there is a UI and you don't have to look up file descriptors
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 man 2 read This should probably be mentioned somewhere. Otherwise, great writeup. Thanks for sharing! (edited)
There's a manpage bash-builtins in section 7, but I've never seen a system that had manpages for the individual builtins, let alone having them in section 1. "man read" on every system I've used opens the read manpage in section 2.
If you think strace is useful, wait until you try dtrace.

My local CentOS 6.2 VM has bash-builtins in section 1, which is where "man read" takes me. Same with a RHEL 6.4 machine in the colo. This might be a distro-specific thing.
So what happened with the Lotus system, and how did strace help?
Running version 7 on my work laptop. :(
We've got a fairly complicated bioinformatics pipeline that calls about 100 other programs, and creates or reads about 100 different files. I'd love a way to create a picture of what's going on. Which files each program uses, etc.
If such a program doesn't exist, would that be worth building? Could it be something I could potentially sell?
