Bash脚本和/bin/bash ^ M:错误的解释器:没有这样的文件或目录 [英] Bash script and /bin/bash^M: bad interpreter: No such file or directory

问题描述

我正在学习本教程，以学习 bash脚本为我自动化一些任务.我正在使用腻子连接到服务器.

I'm learning through this tutorial to learn bash scripts to automate a few tasks for me. I'm connecting to a server using putty.

位于.../Documents/LOG中的脚本为:

#!/bin/bash
# My first script
echo "Hello World!"

然后我对read/write/execute permissions

chmod 755 my_script

然后，当我输入./my_script时，出现标题中给出的错误.

Then, when I enter ./my_script, I'm getting the error given in the title.

一些类似的问题想看看这些，所以我认为它们可能会有所帮助:

Some similar questions wanted to see these, so I think they might help:

which bash

/bin/bash

和

echo $PATH

/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/games:/usr/bin/mh

我尝试将当前目录添加到PATH，但这不起作用.

I tried adding current directory to PATH, but that doesn't work..

推荐答案

在Windows env中创建脚本，然后移植到Unix环境中运行时，我已经看到了这个问题.

I have seen this issue when creating scripts in Windows env and then porting over to run on a Unix environment.

尝试在脚本上运行dos2unix:

http://dos2unix.sourceforge.net/

或者只是使用vi并在测试中重写Unix环境中的脚本.

Or just rewrite the script in your Unix env using vi and test.

Unix使用不同的行尾，因此无法读取您在Windows上创建的文件.因此，它会将^ M视为非法字符.

Unix uses different line endings so can't read the file you created on Windows. Hence it is seeing ^M as an illegal character.

如果要在Windows上写文件然后移植过来，请确保将编辑器设置为以UNIX格式创建文件.

If you want to write a file on Windows and then port over, make sure your editor is set to create files in UNIX format.

在屏幕右下角的notepad ++中，它告诉您文档格式.默认情况下，它将显示Dos\Windows.要更改它，请转到

In notepad++ in the bottom right of the screen, it tells you the document format. By default, it will say Dos\Windows. To change it go to

• 设置->首选项
• 新文档/默认目录标签
• 选择unix格式并关闭
• 创建一个新文档
