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

# clean
echo "************"
echo "clean project"
rm ./bin/*
echo "clean complete"
echo "************"
# compile link
echo "************************"
echo "gcc start"
gcc fork_parent_first.c -o ./bin/fork_parent_first
gcc fork_child_first.c -o ./bin/fork_child_first
echo "gcc complete"
echo "************************"
