Linux strace Commands

First, Introduction

Strace is commonly used to track system calls and received signals when a process executes. In the Linux world, processes cannot directly access hardware devices, and when a process requires access to a hardware device (such as reading a disk file, receiving network data, and so on), it must be switched from user mode to kernel mode and access to the hardware device through system calls. Strace can trace the system calls generated by a process, including parameters, return values, and time spent executing.
