wzl_mysh Introduction ============ This software is the WZL Persional Shell, used to receive command and execute it. It now can support some common commands such as 'ls(-l)', 'date','rm','rmdir', etc. But its function is still weak, we will improve it in the near future. In the exec() function, we use fork and execv functiom: First we do a fork operation, and make a child process, then we call execv() to execute our command in the child process. The execv(const char *path,char * char argv[]) execute the file standed for by *path. In the parent process, we just wait the child's exit. Software Manual =============== 1. How to compile and link? just type: "make" in the your shell. 2. How to use it? just type: "./wzl_mysh". 3. How to get help? just type: "help" in the wzl_mysh. 4. Executable command in the wzl_mysh: help exit ls [-l] date mkdir rm rmdir kill who cd pwd time cat more chmod history echo wc 5. Directory 123,link-file 789,common files 456 and 45***56 are used to validate the function. 6. Also it can execute user's programs Author's Information ==================== Author name: Zhenglei Wang Student number: 1120070388
