This is especially true of UNIX environments, where all of the familiar utilities like ls, rm, grep, and cat are actually separate executables that can be called directly:Python >>> # Linux or macOS >>> import subprocess >>> subprocess.run(["ls"]) timer.py CompletedProcess(args=['ls'...

进程grep在等待输入(即I/O)时的状态称为阻塞,此时grep命令都无法运行 其实在两种情况下会导致一个进程在逻辑上不能运行, 1. 进程挂起是自身原因,遇到I/O阻塞,便要让出CPU让其他进程去执行,这样保证CPU一直在工作 2. 与进程无关,是操作系统层面,可能会因为一个进程占用时间过多,或者优先级等原因,而调用其他的...
