Script Overview Here’s a detailed breakdown of the script:

Checking Input Argument: The script checks if the input file is provided as an argument. if [ -z "$1" ]; then echo "Usage: $0 " exit 1 fi

Initialization: It initializes log and password files and ensures the secure directory exists.

Function to generate a random password

generate_password() {

# using 'openssl rand -base64 12’ to generate a 12-character password
openssl rand -base64 12

}

Read input file line by line

while IFS=';' read -r username groups; do # Create groups if they don't exist for group in $(echo "$groups" | tr ',' ' '); do groupadd "$group" 2>/dev/null || echo "Group $group already exists" done

create user useradd -m "$username" -G "$groups" 2>/dev/null || echo "User $username already exists"

command that sets passwords password=$(generate_password) echo "$username:$password" | chpasswd

Command that logs actions echo "$(date '+%Y-%m-%d %H:%M:%S') - Created user $username with groups: $groups" >> "$log_file"

Command that stores password securely echo "$username:$password" >> "$password_file" done < "$input_file"

Conclusion This script simplifies managing users and groups on a Linux system, ensuring security and efficiency. Automating these tasks not only saves time but also reduces the risk of human error.
