while : do echo "This is another infinite loop." sleep 1 done 在这两个例子中,true和:命令总是返回状态码0(表示成功),因此循环会无限进行下去。 说明如何安全地中断bash中的无限循环: 要安全地中断Bash中的无限循环,可以使用Ctrl+C组合键。这将发送一个中断信号给正在运行的脚本或命令,强制其停止执行。
Bash Infinite while Loop The infinite loops are used for many purposes in Bash scripting, such as testing, debugging, event handling, and managing background processes. The while loop stands as one of the crucial loop structures, often employed to construct infinite loops. The syntax of the whi...
Example 1: Infinite While loop in a shell script An infinite While loop means your script will run the loop commands non-stop. Infinite While loops never stop running and this occurs when the condition always turns out to be “True.” You can create an infinite While loop with the followin...
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。

The condition may be tested at the beginning, or the end of the loop. This loop generally uses a while loop construct. The infinite loop repeats the execution of a section of code forever or until an exception arises. This loop often uses a while true loop construct and is sometimes ...
