如何在shell中分割字符串 [英] How to split a string in shell

问题描述

我有一个变量

string="ABC400p2q4".

如何分隔 ABC400 和 p2q4 .我需要将其分成两个变量，这样我就可以得到

how can I separate ABC400 and p2q4. I need to separate it in two variables in such a way that as a result I get

echo $var1
ABC400
echo $var2
p2q4

可以使用任何字母字符代替ABC.代替400可以有任何其他数字；但是 p 和 q 是固定的，并且也可以代替2和4.

In place of ABC there can be any alphabetic characters; in place of 400 there can be any other digits; but p and q are fixed and in place of 2 and 4 as well there can be any digit.

推荐答案

由于它们是固定长度的子字符串，因此无需基于正则表达式模式进行拆分.在纯 bash 中，您可以执行以下操作:

No need to split based on a regexp pattern as they are fixed length substrings. In pure bash you would do:

$ string="ABC400p2q4"

$ var1=${string:0:6}

$ var2=${string:6}

$ echo $var1
ABC400

$ echo $var2
p2q4
