Linux BASH循环的递归
我还有一个问题。这段代码是为我正在制作的Linux发行版中的rcS脚本编写的，由于某些原因，它偶尔会出错。大约85%的时间它工作正常，一切都很好。但是，有15%的时间它在创建目录或装载时出错Linux BASH循环的递归,linux,bash,loops,for-loop,Linux,Bash,Loops,For Loop,我还有一个问题。这段代码是为我正在制作的Linux发行版中的rcS脚本编写的，由于某些原因，它偶尔会出错。大约85%的时间它工作正常，一切都很好。但是，有15%的时间它在创建目录或装载时出错 # Find and mount all detected drives sda-sdm and partitions 0-10, you can change these by changing the values but odds are you won't have more than 26
