I believe there might be a typo in the command you provided, as "extrace" is not a recognized command. However, assuming you meant "strace" instead of "extrace," here's an explanation:
The command "sudo strace -d" is used to run a program or command with root privileges (using the "sudo" command), while also tracing and logging the system calls made by that program (with the "strace" command).
The "-d" option in the command adds additional debug information to the output. It displays the relative time, in milliseconds, of each system call as it occurs. This can be helpful for identifying performance bottlenecks and analyzing the behavior of a program at a low level.
Overall, this command is often used by system administrators, developers, or troubleshooting experts to diagnose and resolve issues related to system calls and program execution.
