do_rm.h

linuxunix 下的c语言实现

void do_rm(char *fname){
	if(fname == NULL){
		 perror("Waring: at least 1 parameter for rm command of CORAL SHELL\n");
		 return;
	 }


	DIR * dir;
     struct dirent * ptr;
     dir =opendir(".");
 
     while((ptr = readdir(dir))!=NULL)
     {
                if(!(strcmp(fname, ptr->d_name))){
					if(remove(fname) !=0 ){
						perror("ERROR: a error occurs when unlink file!\n");
						break;
					}
					printf("RM file/dir  %s  is complete!\n",ptr->d_name);
					break;
				}
     }

     closedir(dir);
}
