bash - 在ubuntu中运行脚本文件

Question

我正在尝试运行名为 freecs.sh 的开源聊天服务器 freecs(http://freecs.sourceforge.net/) 的脚本文件。当我用 ./freecs.sh 运行文件时，我得到以下信息:bash: ./freecs.sh:/bin/sh^M: bad interpreter: No such file or directory即使该文件存在于同一目录中。当我尝试使用 bash freecs.sh 运行它时，我得到了这个:freecs.sh: line 12: $'\r': command not found

freecs.sh: line 16: $'\r': command not found
freecs.sh: line 19: $'\r': command not found
freecs.sh: line 22: $'\r': command not found
freecs.sh: line 30: $'\r': command not found
freecs.sh: line 33: $'\r': command not found
freecs.sh: line 36: $'\r': command not found
freecs.sh: line 40: $'\r': command not found
freecs.sh: line 43: $'\r': command not found
freecs.sh: line 49: $'\r': command not found
freecs.sh: line 50: like: command not found
freecs.sh: line 51: syntax error near unexpected token `$'{\r''
'reecs.sh: line 51: `echo_failure() {

我已经尝试过 chmod +x freecs.sh 然后运行脚本但没有帮助。该文件如下所示:

谁能告诉我为什么 freecs.sh 找不到文件？和 bash freecs.sh 为什么我得到一个错误？我的 java 主目录设置正确。

谢谢

Answer 1

那是因为你的文件有dos风格的换行符号。

运行

dos2unix freecs.sh

然后像往常一样运行它。

如果 dos2unix 没有安装，你可以试试:

sed -i 's/\r//g' freecs.sh

附言。为了防止将来出现此类错误，您始终可以使用 sed -n l filename 检查此类符号。
