`strace` is a diagnostic, debugging and instructional userspace tracer for Linux.  It is used to monitor and tamper interactions between userspace processes and the Linux kernel, which include system calls, signal deliveries, and changes of process state.  The operation of `strace` is made possible by the kernel feature known as [[http://man7.org/linux/man-pages/man2/ptrace.2.html|ptrace]].
