Infinite for loop can be created with empty expressions, such as: #!/bin/bashfor(( ; ; ))doecho"infinite loops [ hit CTRL+C to stop]"done Conditional exit with break You can do early exit with break statement i
可以使用空表达式创建Infinite for循环,比如 #!/bin/bashfor (( ; ; ))do echo “infinite loops [ hit CTRL+C to stop]”done 带断点的条件退出 您可以在for循环中使用break语句提前退出。您可以使用break从FOR、WHILE或UNTIL循环中退出。for循环中的General break语句 for I in 1 2 3 4 5do statements1...

How do I set infinite loops using for statement? How do I use three-parameter for loop control expression? A 'for loop' is a bash programming language statement which allows code to be repeatedly executed. A for loop is classified as an iteration statement i.e. it is the repetition of a...
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。
Infinite Loops Infiniteforloops do not have a condition set to terminate the loop. The program runs endlessly because the end condition does not exist or never fulfills. To generate an infiniteforloop, add the following code to a Bash script: ...
In an infinite loop, the loop will keep executing until or unless you stop it by yourself by pressing Control + C. #!/bin/bash for (( ; ; )) do echo "Hello There!" done In the example above, the string given will be executed again and again until you stop the loop by yourself...
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...
