Linux
- 整体功能:如果调用的进程不是一个组的组长时,setsid创建一个新会话。调用进程将成为该新会话的组长,新进程组的组长,并且没有控制终端。-The overall function: if the call process is not a group leader, setsid create a new session. Call process will become the new session of the group leader, the new process group lea
12
- 实现一个简单的shell,实现步骤:(1)在虚拟的shell界面上出现命令提示符($或#); (2)获取用户指令:获取用户在命令提示符后面输入的命令及其参数,并注意命令输入的最大长度; (3)解析指令:对用户输入的命令进行解析,解析出命令名和参数; (4)寻找命令文件:每个命令的执行都必须依靠对应的可执行文件,这些文件的存放路径存放在用户的PATH环境变量里; (5)执行命令:可通过fork( )系统调用创建一个进程来完成执行命令的任务,具体的命令执行用execv( )函
