How to pass variables from a file as arguments (options) to a script?
问题
I have a text file with variables in format VARIABLE=value like:
PID=123123
WID=569569
TOKEN=456456456
Where VARIABLE has only uppercase letters and value contains only alphanumeric characters ([a-zA-Z0-9])
Now I want to pass these variables to a script as named arguments (options):
./script.sh --PID 123123 --WID 569569 --TOKEN 456456456
Is there a simple way to do this in bash?

读取文件，以 = 分隔元素，并构建参数数组。然后调用脚本。
args=()
while IFS== read -r k v; do
args+=("--$k" "$v")
done < yourtextfile.txt
./script.sh "${args[@]}"
英文:
Read the file line by line as = separated elements and construct the array of arguments. Then call the script.
args=()
while IFS== read -r k v; do
args+=("--$k" "$v")
done < yourtextfile.txt
./script.sh "${args[@]}"
