A system spends most of its time in a single runlevel, but when you shut the machine down, init switches to a different runlevel in order to terminate the system services in an orderly fashion and to tell the kernel to stop 在Linux系统上的任何时刻,都会运行一定的基本进程(如crond和udevd)。
In Chapter 1, you learned that when one process wants to start another process, it invokes the fork() system call to spawn a copy of itself, and then the copy uses a member of the exec() family of system calls to start running a new program. The strace command begins working on the...

On Unix/Linux usestrace -f -e trace=open(or… trace=file) to see which files are fail reading. Mind redirecting stderr into a file (2>/tmp/trace.log). On Windows use one of these tools: SysinternalsProcess Monitor— use the "Not Found" search —,Process ExplorerorListDLLs ...
For brevity, we useumaskto mean both the actual mask and the command that handles it under Linux. Although the positions of permissions digits matter, they are taken as stand-alone numbers when we convert to other number systems. We tested the code in this tutorial on Debian 12 (Bookworm)...
