动机

用于测试的一组程序比较多，每次编译命令麻烦，写个shell自动执行。

示例

简单示例

# cleanecho \"************\"echo \"clean project\"rm ./bin/*echo \"clean complete\"echo \"************\"# compile linkecho \"************************\"echo \"gcc start\"gcc fork_parent_first.c -o ./bin/fork_parent_firstgcc fork_child_first.c -o ./bin/fork_child_firstecho \"gcc complete\"echo \"************************\"
