timeout 5s ./infinite_loop.sh 提供避免bash无限循环的建议 始终添加退出条件:在编写无限循环时,务必确保有一个明确的退出条件,以避免脚本永远无法停止。 使用合理的循环控制:根据实际需求选择合适的循环结构(如for、while、until等),并合理控制循环次数或条件。 监控脚本执行:在生产环境中运行脚本时,建议进行监控...
bash调用infinite_loop.bash在Pi的每个核心上运行,这个脚本还在所需的时间内每5秒显示Pi的报告温度。脚本工作得很好(导致所有内核都达到100%并产生观察到的温度升高),但是有一个方面不工作,那就是在infinite_loop.bash脚本的末尾试图杀死cpu_spike.bash进程!因此,在我所遵循的示例代码中< 浏览0提问于2018-01-03得...

trap "echo 'Infinite loop detected!'; exit 1" SIGINT 在循环体内部,可以使用sleep命令来暂停一段时间,以避免CPU过度占用。 代码语言:txt 复制 while true; do # 循环体代码 sleep 1 done 当循环变得无限时,如果按下Ctrl+C组合键,将会发送SIGINT信号给脚本。信号处理函数将会被调用,输出一条消息并退出脚本。
Shell or bash allows you to enter “arguments” while writing scripts. These arguments are interpreted as variables in your bash script. Commonly, bash's positional arguments are used to add information, context, or meaning to a shell script. WHILE Infinite Loop On its own, a WHILE loop will...
