Help with bash script

Shell Scripting
#1

Can someone please help with this bash script. I am trying to get all the untagged log groups in an aws account. I am using aws cli api command where i need to paginate the request due to the many records. But for reason, the nextToken is not working, it keeps generating the same first 50 records.

#!/bin/bash

# AWS profile (optional)
AWS_PROFILE="xxx"

# AWS region
AWS_REGION="us-east-1"

# Output CSV file
CSV_FILE="untagged_log_groups.csv"

# Header for CSV file
# Check if CSV file already exists
if [ ! -f "$CSV_FILE" ]; then
    # If CSV file doesn't exist, create it and add header
    echo "LogGroupName" > $CSV_FILE
fi

ITERATION_COUNT=0


# Function to list log groups with pagination
list_log_groups() {
    aws logs describe-log-groups --query 'logGroups[*].logGroupName' --output text --profile "$AWS_PROFILE" --region "$AWS_REGION" --max-items 50
    echo "Done list_log_groups"
}

LOG_GROUPS=()

# Iterate through log groups with pagination
next_token=""
while true; do
    ((ITERATION_COUNT++))
    echo "Iteration count: $ITERATION_COUNT"
    LOG_GROUPS=$(list_log_groups "$next_token")
    echo "Retrieved log groups: $LOG_GROUPS"
    for LOG_GROUP in $LOG_GROUPS; do
        # Check if the log group has tags
        TAGS=$(aws logs list-tags-log-group --log-group-name "$LOG_GROUP" --query 'tags' --output text --profile "$AWS_PROFILE" --region "$AWS_REGION")
        echo "TAGS"

        # If no tags found, extract log group details
        if [ -z "$TAGS" ]; then
            echo "$LOG_GROUP" >> "$CSV_FILE"
        fi
    done

    # Check if there are more log groups to fetch
    next_token=$(aws logs describe-log-groups --query 'nextToken' --output text --profile "$AWS_PROFILE" --region "$AWS_REGION")
    echo "printing next token: $next_token"
    if [ -z "$next_token" ] || [ "$next_token" == "None" ]; then
        break
    fi
done

echo "CSV file updated: $CSV_FILE"

You are fetching the next token but I’m not seeing where you are using it?

Thank you so much. I refactored the code and now I could get the untagged resources.
