- Direct Execution: execve() directly executes a program, bypassing the shell. This avoids vulnerabilities like shell injection, which can occur with system() if user input is not properly sanitized. - Controlled Environment: With execve(), you can explicitly specify the environment variables for the new process, providing better control over the execution context. - No Shell Overhead: execve() does not invoke a shell, reducing the risk of unintended behavior caused by shell features or configurations. - Predictable Behavior: execve() only executes the specified program, whereas system() relies on the shell, which may interpret commands differently based on the shell's configuration or environment.
