linux strace - cheyiliu/All-in-One GitHub Wiki
In the simplest case strace runs the specified command until it exits. It intercepts and records the system calls which are called by a process and the signals
which are received by a process. The name of each system call, its arguments and its return value are printed on standard error or to the file specified with the -o
option.
strace is a useful diagnostic, instructional, and debugging tool.
