比较两个数组在bash，diff和值相同 [英] Compare two arrays in bash, diff and identical values

问题描述

这个问题指的是回答问题：
<一href=\"http://stackoverflow.com/questions/2312762/compare-difference-of-two-arrays-in-bash\">Compare/Difference在bash 两个数组

This question refers to the answered question: Compare/Difference of two arrays in bash

让我们两个数组：

Array1=( "key1" "key2" "key3" "key4" "key5" "key6" "key7" "key8" "key9" "key10" "key13" )
Array2=( "key1" "key2" "key3" "key4" "key5" "key6" "key11" "key12" "key13" )

阵列之间的差异对称：

Symetrical Differences between arrays:

Array3=(`echo ${Array1[@]} ${Array2[@]} | tr ' ' '\n' | sort | uniq -u `)

ARRAY3值：

Array3 values:

echo $Array3
key10
key11
key12
key7
key8
key9

值仅在数组1：

echo ${Array1[@]} ${Array3[@]} | tr ' ' '\n' | sort | uniq -D | uniq
key10
key7
key8
key9

值仅在ARRAY2

Values only in Array2

echo ${Array2[@]} ${Array3[@]} | tr ' ' '\n' | sort | uniq -D | uniq
key11
key12

我的问题，我们如何能够得到在数组1＆安培值;数组2，但不是在ARRAY3（相同）？
预期结果：

My question, how can we get values that are in Array1 & Array2 but not in Array3 (identical)? Expected result:

key1
key13
key2
key3
key4
key5
key6

感谢您的帮助。

推荐答案

确定一些测试之后，似乎我一直在寻找的答案只是：

OK after few test, it seems the answer I was looking for was just:

echo ${Array1[@]} ${Array2[@]} | tr ' ' '\n' | sort | uniq -D | uniq
key1
key13
key2
key3
key4
key5
key6
