在Bash For Loop中使用“Continue”语句 “ continue ”语句是控制脚本运行方式的内置命令。除了bash脚本之外,它还用于Python和Java等编程语言。continue语句在满足特定条件时停止循环内的当前迭代,然后恢复迭代。可以看看如下所示的for循环。 #!/bin/bash for n in {1..10} do if [[ $n -eq '6' ]] then ...
/bin/bashfornin{1..7};doecho $n done 执行shell 脚本后,将列出范围内的所有值,类似于我们在简单循环中的情况。 此外,我们可以在范围的末尾包含一个值,该值将导致 for 循环以增量步骤迭代这些值。 以下bash 脚本打印 1 到 7 之间的值,从第一个值开始在这些值之间增加 2 个步长。 代码语言:javascript ...
