Shell脚本while循环，用于将文件转换为变量

Question

So I have a snippet of the excel forms, and I am trying to use bash script to convert them into a format we want.
The file looks like this:
Group1 Member1
********** Member2
********** Member123
Group2 Member183
**********Member1023

So on and so forth....
What the file means, is that it's essentially a form. Where it tells you that Group 1 has the member of "Member1" "Member2""Member123". THe " ** "means it's a blank field. I am trying to use a while loop to read all the group names (column1) into variable $Groupname and all the members (column2) into variable $Groupmember, and then use awk to print something like this:
Group 1 Member1
Group 1 Member2
Group 1 Member123
So how can I do that?

Answer 1

Ok, assuming I understand your question correctly, you could do something like this:

input.txt

Group1 Member
********* Member2
********* Member123
Group2 Member183
********* Member1023

Then in a bash script, you could keep track of the most recent group used:

#!/bin/bash

CURRENTGROUP=""

while read -r group member
do
        if [[ ${group:0:1} != "*" ]]; then
                CURRENTGROUP=$group
        fi

        echo "$CURRENTGROUP $member"

done < "input.txt"

Which produces the following output:

Group1 Member
Group1 Member2
Group1 Member123
Group2 Member183
Group2 Member1023
