shell-定义一个颜色输出字符串函数

写法 1

1function echo_color(){
2    if [ $1 == "green" ]; then
3        echo -e "\033[32;40m$2\033[0m"
4    elif [ $1 == "red" ]; then
5        echo -e "\033[31;40m$2\033[0m"
6    fi
7}
8echo_color green "我是绿色"
9echo_color red "我是红色"

写法 2 也可以在前面不写function，也可以定义函数

1echo_color(){
2case $1 in
3green)
4    echo -e "\033[32;40m$2\033[0m"
5;;
6red)
7    echo -e "\033[31;40m$2\033[0m"
8;;
9*)
10    echo "Example: echo_color red string"
11esac
12}
13echo_color green "我是绿色"
14
