How do I use the splitfunction to split by "\."?

如何使用split函数以“\.”分割?

For example, first consider splitting by ::

例如,首先考虑拆分为:

echo "03:26:12" | awk '{split(
122603
,a,":"); print a[3] a[2] a[1]}'

Which produces this output:

产生这个输出:

echo "03\.26\.12" | awk '{split(
122603
,a,???); print a[3] a[2] a[1]}'

But if the incoming string is instead:

但是如果传入的字符串是:

echo "03\.26\.12" | awk '{split(
122603
,a,/\\./); print a[3] a[2] a[1]}'

With desired output:

具有所需的输出:

echo "03\.26\.12" | awk '{split(##代码##,a,"\\."); print a[3] a[2] a[1]}'

What should the ???be?

应该???是什么?
