Description: 一个自己写的shell，其功能如下：
1) cd <directory> ——把当前默认目录改变为<directory>。如果没有<directory>参数，则显示当前目录。如该目录不存在，会出现合适的错误信息。这个命令也可以改变PWD 环境变量。
2) clr ——清屏。
3) <directory> ——列出目录<directory>的内容。
4) environ ——列出所有的环境变量。
5) echo <comment> ——在屏幕上显示<comment>并换行（多个空格和制表符可能被缩减为一个空格）。
6) help ——显示用户手册，并且使用more 命令过滤。
7) quit ——退出shell
-Write their own shell, its function as follows:
1) cd <directory>- The current default directory is changed to <directory>. If there is no <directory> parameter, it displays the current directory. If the directory does not exist, there will be an appropriate error message. This command can also change the PWD environment variable.
2) clr- clear the screen.
3) <directory>- list directory <directory> content.
4) environ- lists all environment variables.
5) echo <comment>- Display <comment> on the screen and a line feed (multiple spaces and tabs may be reduced to a single space).
6) help- displays the user s manual, and use the more command filtering.
7) quit- quit shell

Description: Your shell prompt MUST adhere to the following format:
o Current date (optional) and time (mandatory) followed by the hash sign (e.g., 13:03:00#)
Your shell MUST support, at minimum, the following commands: o The internal shell command “exit” to terminate the shell o ls, with no arguments
o ls, with arguments (e.g., ls –l)
o echo
Your shell WILL NEED system calls fork(), waitpid(), and one of execv, execve or execvp. You MUST
NOT use the C library function system(). You WILL receive a grade of zero if you do so.
You MUST check and correctly handle all return values. This means that you need to read the man pages for the system calls to figure out what the possible return values are and the types of errors
they indicate, and what you must do when you get that error.
