timeout命令默认运行在单独的进程组中,而终端的ctrl+c的SIGINT信号只发送给脚本,timeout命令接收不到。而脚本被timeout进程给阻塞了,要在timeout命令结束之后才会接收SIGINT信号。 想让timeout命令接收到终端的ctrl+c发送的SIGINT的信号,需要加上参数--foreground,这样timeout命令就会继承父进程的进程组。例子: timeout --foreground 1h sleep 1m

This Bash shell script executes a command with a time-out. Upon time-out expiration SIGTERM (15) is sent to the process. If the signal is blocked, then the subsequent SIGKILL (9) terminates it. This should work on any Linux distribution with Bash. Popular Posts: None Found Tuesday Februar...

However,if we just spawn child processes in a Bash script, the script might exit before the child process has finished. We can use thewaitcommand to wait for a child process to exit: $sleep5 & $wait;echoSlept Slept [1]+ Donesleep5 ...
这里要提示一下script一般有2种写法: 通过脚本执行的返回结果,改变优先级,keepalived继续发送通告消息,backup比较优先级再决定 脚本里面检测到异常,直接关闭keepalived进程,backup机器接收不到advertisement会抢占IP killall -0 nginx属于第1种情况,/etc/keepalived/check_nginx.sh属于第2种情况(脚本中关闭keepalived)。个人...

在ReactJS中,setTimeout函数的行为可能会出现一些奇怪的情况。setTimeout是JavaScript中的一个函数,用于在指定的时间间隔后执行一段代码。然而,在ReactJS中,由于其虚拟DOM的特性,setTimeout的行为可能会与我们预期的不同。 ReactJS通过使用虚拟DOM来提高性能,它会将组件的状态和属性与实际的DOM进行比较,并只更新需要...
Scripts(脚本语言)、Shell、Sh、Bash之间的关系Scripts脚本(Script),是一种特定的描述性语言,依据一定的格式编写的可执行文件。脚本语言与编译语言不同,用脚本语言写出的脚本文件可以直接作为可执行文件运行,无需像C或C++语言那样先编译再运行。脚本执行时,计算机会执行一连串的操作,脚本文件将不同的命令组合起来,并按照...
