I have a file that I have some functions to be used by a script.
So in my script I do the following:
source my_functions.sh VALUE_A=$(get_proper_value "X") [[ -z "$VALUE_A" ]] && echo "Missing value" && exit 1 THE_URL=$(get_url_of_service "SERVICE_NAME") [[ -z "$THE_URL" ]] && echo "Missing URL" && exit 1 CUSTOMER_ID=$(generate_customer_id "Z") [[ -z "$CUSTOMER_ID" ]] && echo "Missing customer id" && exit 1 etc
I have 4-5 more such declarations at the top of my script before actually doing any processing.
This seems to clutter the script.
Is there a better approach for this? I was thinking of declaring the variables inside
my_functions.sh but I was wondering if that could make it worse as it won’t be clear where these variables are coming from
