Shell中文本或CSV文件中的数组值 [英] Array Values from Text or CSV File in Shell

问题描述

我有一个脚本，其中声明了如下数组:

I am having a script in which I am declaring arrays like below:

declare -a Pool=("Terrace|HouseTerrace_")
declare -a Library=("lib1 lib2 lib3")
declare -a Name=("Guru/Raju Albert Deepak")
declare -a Email=("[e-mail],[e-mail] [e-mail] [e-mail]")
Sub=("Media Rotation")
i=0
while [ $i -lt ${#Pool[@]}  ]
do
command blah balh blah
i=`expr $i + 1`
done

现在我想要的是代替在此处声明aaray的值，我应该从文件(text或csv)中将其导入，或者有没有更好的方法来执行此任务.我不想将脚本文件的访问权限授予用户.

Now what i want is that instead of declaring values in aaray here i should import it from file (either text or csv ) or is there any better way perfroming this task. I don want to give access to script file to users.

推荐答案

这是部分答案，以帮助启动OP工作.

This is a partial answer, to help kick-start the OP effort.

bash"readarray"可用于从文件加载数组.例如，它们的代码declare -a email=("[e-mail]" "[e-mail]" ...)可以替换为

The bash "readarray" can be used to load an array from a file. For example they code declare -a email=("[e-mail]" "[e-mail]" ...) can be replaced with

readarray email < email.txt

email.txt在哪里(使用发布的数据)

Where email.txt is (using posted data)

[e-mail]
[e-mail]
[e-mail]
...

另一个建议的改进将是使用for item in而不是while循环来遍历数组.代替i=0 ; while [ $i -lt ${#Pool[@]} ] ; do ... ; done

Another suggest improvement will be to use for item in instead of while loops to iterate over arrays. Instead of i=0 ; while [ $i -lt ${#Pool[@]} ] ; do ... ; done

for p in "${pool[@]}" ; do
   command $p
done
