-rwxr-xr-x 1 root root 179 Jun  6 18:19 /etc/start.sh

输出/etc/start.sh

-bash: /etc/start.sh: /bin/bash^M: bad interpreter: No such file or directory

答案1

我在 Windows 上使用 Notepad++，所以我必须运行

sed -i -e 's/\r$//' /etc/start.sh

替换 Windows 行结尾。

^M 是回车符。 Linux 使用换行符来标记行结束，而 Windows 使用两个字符序列 CR LF。您的文件具有 Windows 行结尾，这会让 Linux 感到困惑。
