bash 关联数组的基本错误值非常大

发布于 2024-10-17 21:11:44 字数 505 浏览 2 评论 0原文

我有一个名为 a.txt 的文件，如下所示

7A1123123asd 14
8aasdasdasd 15

现在我编写了一些 bash 代码来读取该文件并根据其中的值构建关联数组

#!/bin/bash
declare -a counter
while read DEAL count; do
    counter["$DEAL"]=$count
done < oasload.job

for i in "${!array[@]}"
do
    echo "key : $i"
    echo "value : ${array[$i]}"
done

不幸的是，当我运行时，出现以下错误

test.sh: line 6: 7A1123123asd: value too great for base (error token is "7A1123123asd")

任何帮助表示赞赏。

I have a file called a.txt which looks as follow

7A1123123asd 14
8aasdasdasd 15

Now I wrote some bash code to read the file and build an associative array from the values in it

#!/bin/bash
declare -a counter
while read DEAL count; do
    counter["$DEAL"]=$count
done < oasload.job

for i in "${!array[@]}"
do
    echo "key : $i"
    echo "value : ${array[$i]}"
done

Unfortunately when I run I get the following error

test.sh: line 6: 7A1123123asd: value too great for base (error token is "7A1123123asd")

Any help appreciated.

看起来 bash 将以数字开头的键视为数字。因此，尝试转换 7A 时它会犹豫，因为 A 不是有效的 10 进制数字。例如，如果您可以在所有键上加上 X 前缀，那么这应该可以修复它。

#!/bin/bash
declare -a counter
while read DEAL count; do
    counter["X$DEAL"]=$count
done < oasload.job

for i in "${!array[@]}"
do
    echo "key : $i"
    echo "value : ${array[$i]}"
done

Looks like bash treats keys starting with digits as numeric. So, trying to convert 7A it balks because A is not a valid base-10 digit. If you can e.g. prefix all your keys with X throughout, this should fix it.

#!/bin/bash
declare -a counter
while read DEAL count; do
    counter["X$DEAL"]=$count
done < oasload.job

for i in "${!array[@]}"
do
    echo "key : $i"
    echo "value : ${array[$i]}"
done

一切看起来都不错，除了在 Bash 4 中，关联数组是用 -A 声明的。 4 之前的版本不支持关联数组。任何版本中的索引数组都使用 -a 声明，或者使用 array[7]="element" 或 array=( 等语法在赋值时自动创建abc def ghi 123 456)。

#!/bin/bash
declare -A counter
while read DEAL count; do
    counter["$DEAL"]=$count
done < oasload.job

for i in "${!array[@]}"
do
    echo "key : $i"
    echo "value : ${array[$i]}"
done

Everything looks OK except that in Bash 4, associative arrays are declared with -A. Versions prior to 4 do not support associative arrays. Indexed arrays in any version are declared using -a or they are created automatically on assignment using syntax such as array[7]="element" or array=(abc def ghi 123 456).

#!/bin/bash
declare -A counter
while read DEAL count; do
    counter["$DEAL"]=$count
done < oasload.job

for i in "${!array[@]}"
do
    echo "key : $i"
    echo "value : ${array[$i]}"
done
