builtins.c 中的 do_kill 函数是否多余？

[So-Ezzz]

要求的内置命令中并没有kill，与 builtins.c 中的描述并不一致

/*
 * builtins.c - Implementation of built-in shell commands
 *
 * This file implements built-in commands such as:
 *   - quit: Exit the shell.
 *   - cd: Change the current working directory.
 *   - jobs: List background and stopped jobs.
 *   - fg: Bring a background job to the foreground.
 *   - bg: Resume a stopped job in the background.
 *   - kill: Terminate a job.
 *
 * Complete the implementations as specified.
 */

那么该函数是否多余？

void do_kill(command_t *cmd) {
  /* TODO: Implement the functionality for kill command.
     - Terminate a job with the specified job ID.
     - Handle both foreground and background jobs.
     - Send the SIGKILL signal to the job.
  */
}
