资 源 简 介
1. 编写一个C程序作为Linux内核的shell命令行解释程序。Shell程序应该使用与Bource shell相同的方式运行程序。 2. 增加功能以使用户可以使用"&"操作符作为命令的结束符。一个以"&"结尾的命令应该与shell并发执行。 3. 增加功能以使用户可以使用"<"和">"作为文件名前缀来重定向stdin和stdout描述符。同样，允许用户使用管道操作符" "来同时执行两个进程，并把第一个进程的stdout重定向为第二个进程的stdin。-1. Preparation of a C program as a Linux kernel shell command line interpreter. Shell procedures should be used with Bource shell the same way as operational procedures. 2. Increased functionality so that customers can use, "" operator, as ordered by the end tags. A "" the end of the order should be concurrent with the implementation of the shell. 3. Increased functionality so that customers can use "lt;" "Gt;" As a filename prefix to redirect stdin and stdout descriptors. Similarly, allows users to use pipeline operator, "" two parallel processes, and a process to redirect stdout second process stdin.
