如何在bash shell中将一个字符串拆分为多个变量? [英] How to split one string into multiple variables in bash shell?

问题描述

我一直在寻找解决方案并发现了类似的问题，只是他们试图用空格分隔句子，而这些答案不适用于我的情况.

I've been looking for a solution and found similar questions, only they were attempting to split sentences with spaces between them, and the answers do not work for my situation.

目前一个变量被设置为这样的字符串:
ABCDE-123456
我想把它分成 2 个变量，同时消除-".即:
var1=ABCDE
var2=123456

Currently a variable is being set to something a string like this:
ABCDE-123456
and I would like to split that into 2 variables, while eliminating the "-". i.e.:
var1=ABCDE
var2=123456

怎么可能做到这一点?

这是对我有用的解决方案:
var1=$(echo $STR | cut -f1 -d-)
var2=$(echo $STR | cut -f2 -d-)

This is the solution that worked for me:
var1=$(echo $STR | cut -f1 -d-)
var2=$(echo $STR | cut -f2 -d-)

是否可以使用 cut 命令而无需分隔符(每个字符都设置为变量)?

Is it possible to use the cut command that will work without a delimiter (each character gets set as a variable)?

var1=$(echo $STR | cut -f1 -d?)
var2=$(echo $STR | cut -f1 -d?)
var3=$(echo $STR | cut -f1 -d?)
等

推荐答案

如果你的解决方案不必是通用的，即只需要像你的例子那样处理字符串，你可以这样做:

If your solution doesn't have to be general, i.e. only needs to work for strings like your example, you could do:

var1=$(echo $STR | cut -f1 -d-)
var2=$(echo $STR | cut -f2 -d-)

我在这里选择 cut 是因为你可以简单地为更多的变量扩展代码......

I chose cut here because you could simply extend the code for a few more variables...
