在bash中搜索数组返回索引

Question

只是pesuocode,但这基本上是我想做的.

Array=("1" "Linux" "Test system"
       "2" "Windows" "Workstation"
       "3" "Windows" "Workstation")


echo "number " ${array[search "$1"]} "is a" ${array[search "$1" +1]} ${array[search "$1" +2])}

这可能与bash有关吗？我只能找到有关搜索和替换的信息.我没有看到任何可以返回和索引的东西.

这样的东西应该工作:

search() {
    local i=1;
    for str in "${array[@]}"; do
        if [ "$str" = "$1" ]; then
            echo $i
            return
        else
            ((i++))
        fi
    done
    echo "-1"
}

虽然循环遍历数组以找到索引当然是可能的,但这种具有关联数组的替代解决方案更实用:

array=([1,os]="Linux"   [1,type]="Test System"
       [2,os]="Windows" [2,type]="Work Station"
       [3,os]="Windows" [3,type]="Work Station")

echo "number $1 is a ${array[$1,os]} ${array[$1,type]}"
