以下是一个简单的while循环示例,它会一直打印“Hello, World!”直到用户手动停止(例如,通过按Ctrl+C): bash #!/bin/bash counter=1 while [ $counter -le 5 ] do echo "Hello, World! ($counter)" counter=$((counter + 1)) done 在这个示例中,counter 从1开始,每次循环增加1,直到其值大于5时循环...
The loop structure is one of the key components of every programming language including Bash. They are used to repeat the specified instructions against a condition. Frequently employed loop structures in Bash scripting arefor,while, anddo-while. In Bash scripting, thewhileloop functions by repeatin...
