Foreground processes directly interact with the user, like running a command in a terminal window. In contrast, background processes operate silently without requiring user input, such as system monitoring tools or file backups. Some background processes function aslist services– long-running tasks ...
bg: Background chown: Change owner chgrp: Change group chmod: Change mode umount: Unmount dd: 本来应根据其功能描述“Convert an copy”命名为“cc”,但“cc”已经被用以代表“CComplier”,所以命名为“dd” tar:Tape archive (磁带档案) ldd:List dynamic dependencies ...
