Bash脚本从文本文件读取变量

Question

我想在文本文件中包含以下内容

name=missy email=missy@example.com

是否有可能将其读入文本文件并能够调用变量$ name和$ email

或最好的方法是什么？

谢谢你的帮助

当然，这是想到的第一种方式：

#!bash
# set for loop separator to newline
IFS=$'\n'
# loop through each line in the file
for userline in $(cat email_list.txt); do
    # Cut delimiter is a space for the next two lines
    # echo the line into cut, grab the first field as the user
    user=$(echo "$userline" | cut -d' ' -f1)
    # echo the line into cut, grab the second field as the email
    email=$(echo "$userline" | cut -d' ' -f2)

    # Set the delimiter an =, grab field 2
    user=$(echo "$user" | cut -d'=' -f2)
    # Set the delimiter an =, grab field 2
    email=$(echo "$email" | cut -d'=' -f2)

    echo "Username: ${user}, email address: ${email}"
done

email_list.txt：

name=missy email=missy@example.com
name=joe email=joe@smoe.com

输出：

Username: missy, email address: missy@example.com
Username: joe, email address: joe@smoe.com
