记录一个 shell 脚本的坑

比如如下脚本，执行的时候提示

./restart.sh: 行 1: $'\r': 未找到命令

出现这样的错误，是因为 Shell 脚本在 Windows 系统编写时，每行结尾是\r\n，而在 Linux 系统中行每行结尾是\n，所以在 Linux 系统中运行脚本时，会认为\r 是一个字符，导致运行错误。
虽然我是 mac 编写的，但应该也是这个意思吧。

解决方法
去除 Shell 脚本的\r 字符：

方法 1

sed -i 's/\r//' restart.sh

方法 2

dos2unix one-more.sh

如果权限不足：

chmod +x restart.sh
