Tutorial: Debugging with Strace - A Peek Behind the Scenes of Linux Processes - Avikam Rozenfeld, Intel "strace" is a tool that traces system calls and signals of Linux processes. This is a great tool for debugging, diagnostics, or simply learning how processes interact with the Linux kernel behind the scenes. Unfortunately, Linux beginners often overlook this tool or underutilize it, intimidated by its long and complicated-looking output. This is unfortunate because they'll be missing out a great opportunity to dive deeper into Linux internals and take their debugging skills to the next level. Starting to master it is not as difficult as one might think. Understanding how system calls work and learning about the various flags in the tool opens up a whole new world of goodness. The purpose of this session is to unravel the mysteries of strace and show you step-by-step how to tame it. I will explain what system calls are and how they work; review the various flags and arguments for strace; demonstrate the basic methodology for reading and analyzing its output through simple examples; and show some real-life cases where it was used to save the day.
