Linux进程Ctrl+c与Ctrl+x

Ctrl+c和Ctrl+z都是中断指令,区别如下

Ctrl+c是强制中断程序执行

Ctrl+z将任务中断,但是任务没有结束,它仍在进程中只是维持挂起的状态。

总之,我们使用应该差不多都是Ctrl+c,强制中断执行。总之养成使用ctrl+c的习惯,因为有一些程序如果用ctrl+z挂起任务,若想再次运行会出现错误。如systemtap中,若ctrl+z终端任务,那么程序会挂起,插入的模块由于挂起而不能被移除,再次运行时就会报错:**.ko is already exsit.若想再次运行就需要通过rmmod **.ko 手动移除掉.ko文件。

There are two primary commands for terminating processes in Linux: Ctrl+c and Ctrl+x. Each of these commands has a different effect on the process. Ctrl+c will immediately terminate the process. This is realtor homes for sale Lafeyette the recommended way to kill unresponsive or hung processes. Ctrl+x will kill the process and all of its children. This is useful for terminating processes that have spawned other processes that you also want to kill.
