I’m using this tutorial to learn bash scripts to automate a few
tasks for me.
I’m connecting to a server using putty.
The script, located in .../Documents/LOG, is:
#!/bin/bash
# My first script
echo "Hello World!"
And I executed the following for read/write/execute permissions
chmod 755 my_script
Then, when I enter ./my_script, I’m getting the error given in the
title.
Some similar questions wanted to see these, so I think they might
help :
$ which bash
/bin/bash
and
$ echo $PATH
/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/games:/usr/bin/mh
I tried adding the current directory to PATH, but that doesn’t
work …

Run following command in terminal
sed -i -e 's/r$//' scriptname.sh
Then try
./scriptname.sh
It should work.

I have seen this issue when creating scripts in Windows env and then porting over to run on a Unix environment.
Try running dos2unix on the script:
http://dos2unix.sourceforge.net/
Or just rewrite the script in your Unix env using vi and test.
Unix uses different line endings so can’t read the file you created on Windows. Hence it is seeing ^M as an illegal character.
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.
In notepad++ in the bottom right of the screen, it tells you the document format. By default, it will say DosWindows. To change it go to
- settings->preferences
- new document / default directory tab
- select the format as unix and close
- create a new document

This is caused by editing file in windows and importing and executing in unix.
dos2unix -k -o filename should do the trick.

problem is with dos line ending. Following will convert it for unix
dos2unix file_name
NB: you may need to install dos2unix first with yum install dos2unix
another way to do it is using sed command to search and replace the dos line ending characters to unix format:
$sed -i -e 's/r$//' your_script.sh

Your file has Windows line endings, which is confusing Linux.
Remove the spurious CR characters. You can do it with the following command:
$ sed -i -e 's/r$//' setup.sh

I was able to resolve the issue by opening the script in gedit and saving it with the proper Line Ending option:
File > Save As…
In the bottom left of the Save As prompt, there are drop-down menus for Character Encoding and Line Ending. Change the Line Ending from Windows to Unix/Linux then Save.

Вступление
Иногда при запуске различных sh скриптов можно столкнуться вот с такой ошибкой:
bash: ./script.sh: /bin/bash^M: bad interpreter: No such file or directory
В данной статье мы рассмотрим причину возникновения данной ошибки и о способах ее исправления.
Причина возникновения
Как видно из текста ошибки, при запуске скрипта вместо стандартного шелла /bin/bash скрипт пытается запустить его из директории /bin/bash^M и ожидаемо выдает ошибку, потому что такого пути не существует. Все дело в том, что ^M — это символ возврата каретки (окончания строки), который обычно используется на Windows системах. По всей видимости, данный скрипт редактировался каким-либо текстовым редактором, в настройках которого был выставлен режим Windows (а не Linux) и из-за этого, при запуске скрипта получается такая ошибка.
Как исправить ошибку (способ 1: очень быстрый)
Допустим, наш скрипт, при запуске которого мы получаем ошибку будет называться script.sh.
1) Делаем его резервную копию, чтобы иметь возможность восстановить работоспособность, если что-либо пойдет не так.
2) Запускаем следующую команду:
sed -i -e 's/r$//' script.shОна должна заменить все символы переноса строки Windows на те, которые используются на Linux системах. Способ не совсем универсальный, поэтому иногда может не сработать.
3) После выполнения данной команды, пытаемся запустить на скрипт script.sh и проверить работоспособность. Если не помогло, то восстанавливаем оригинал из резервной копии и переходим ко второму способу.
Как исправить ошибку (способ 2: медленный, но очень надежный)
Если первый способ не помог, либо если вы часто сталкиваетесь с такой ошибкой, то можно воспользоваться специальной утилитой dos2unix, которая как раз подходит для таких случаев
1) Делаем резервную копию script.sh, чтобы восстановить его в случае проблем.
2) Устанавливаем утилиту dos2unix
sudo apt update && sudo apt install dos2unix3) Выполняем команду:
dos2unix script.sh
dos2unix: converting file script.sh to Unix format...4) После выполнения данной команды, пытаемся запустить на скрипт script.sh и проверить работоспособность.
I wanted to execute a shell script:
-rwxr-x--x 1 root root 17234 Jun 6 18:31 create_mgw_3shelf_6xIPNI1P.sh
I tried to do a standard procedure, but I got this error:
./create_mgw_3shelf_6xIPNI1P.sh
localhost 389 -l /opt/fews/sessions/AMGWM19/log/2013-06-06-143637_CLA-0

**ERROR sh: ./create_mgw_3shelf_6xIPNI1P.sh: /bin/bash^M: bad interpreter: No such file or directory**
What does it mean? I was doing this as the root user under the root group.
Does it mean that the file does not have the correct permission for the root user?

This isn’t a permission issue, you aren’t getting a message about permissions
/bin/bash^M: bad interpreter: No such file or directory
The script indicates that it must be executed by a shell located at /bin/bash^M. There is no such file: it’s called /bin/bash.
The ^M is a carriage return character. Linux uses the line feed character to mark the end of a line, whereas Windows uses the two-character sequence CR LF. Your file has Windows line endings, which is confusing Linux.
Remove the spurious CR characters. You can do it with the following command:
sed -i -e 's/r$//' create_mgw_3shelf_6xIPNI1P.sh

In vim you could also use :set ff=unix and then save the file, or :set ff=dos to get DOS formatting again.

Your file has DOS/Windows style line endings (CR LF), but on Unix-like systems only the LF control character is used as line break.
The additional CR control character is shown encoded as ^M in your output. You can also see it when you run cat -A create_mgw_3shelf_6xIPNI1P.sh.
To convert the line endings from DOS/Windows style to Unix style, there’s a tool called dos2unix. You install it using:
sudo apt-get install dos2unix
Then you can simply convert files’ line endings in both ways using
dos2unix FILENAME
unix2dos FILENAME
In your case, simply run this command below and the script file will be converted in-place:
dos2unix create_mgw_3shelf_6xIPNI1P.sh
After that Bash should be able to interpret the file correctly.

The Problem ist you edit with Dos!
open your file with vi
then set unix with:
:set ff=unix
:wq
and it all fine

Do vi <your script>.
then :set list; it will display any of the special characters in your script.
then replace the character:
:%s/^M//gc [to type ^M press Ctrl + v + m]

As explained in the other answers, this is a format issue. So, the answer is to change the format from DOS to Unix style line endings. This is yet another simple way to fix your file ‘in place’

It’s available in package tofrodos:
sudo apt-get install tofrodos

You can also use gedit to remove the unwanted characters.
Under the File menu select Save As and set the line end type unix/Linux.

I had developed the bash script on a Mac, so the first line of the script was
#!/opt/homebrew/bin/bash
When I tried to run it on ubuntu, I got the bad-interpreter issue. I changed the first line to
/usr/bin/bash
This change worked on ubuntu which bash command on ubuntu to find the path of bash.

The bin bash m bad interpreter no such file or directory is an error message that occurs due to various problems found with the file path or permissions. This article will explain this error in detail, along with some solutions to fix it. Let’s begin and see why this error is popping up on your screen and what can be done to fix this immediately!

- Conclusion
The bin bash m bad interpreter no such file or directory error occurs when the file does not exist in the specified location. The mentioned error can occur when the script file is not executable or file permission issues exist.
It is important to ensure that the shebang line is properly set and the script file exists in the correct location with the appropriate permissions.
Some other reasons are given below.
- Incorrect shebang line.
- Wrong line endings.
- Missing or bad interpreter.
- Syntax error.
– Incorrect Shebang Line
The shebang line in the script might be incorrect, misspelled, or pointing to a non-existent interpreter. For example, if the shebang line says “#!/bin/bas”, it will not work since there is no such interpreter as “bas”.
– Wrong Line Endings
If the script was created on a Windows system and then copied to a Unix-based system, the line endings might not be correct, causing the shebang line to be interpreted incorrectly. This improper interpretation leads to the error under consideration.
– Missing or Bad Interpreter
The interpreter specified in the shebang line might not be installed or unavailable in the system’s PATH. For example, if the shebang line specifies “#!/usr/local/bin/python”, but if Python is not installed in /usr/local/bin or not in the system’s PATH, the error will occur.
– Permissions
If the script file does not have executable permissions, the interpreter specified in the shebang line cannot execute the script. In a Unix-based system, permissions control who can access and modify files and directories. The permissions of a directory are set using a combination of three types of permissions – read, write, and execute – for three types of users – owner, group, and others.
The owner of the directory is the user who created it, and the group is a set of users who have a certain level of access to the file or directory. A string of characters represents the permissions for each user type: r for read access, w for write access, and x for execute access.
– Syntax Error
The wrong syntax can occur due to any small mistake, such as a typo error or wrong operand at the wrong place. Due to syntax errors, some other errors also occur. They are:
- /bin/bash^m: bad interpreter: no such file or directory wsl.
- /bin/bash^m bad interpreter no such file or directory windows.
- Bin/bash^m: bad interpreter: no such file or directory mac.
- /bin/bash^m bad interpreter no such file or directory linux.
How To Fix Bin Bash M Bad Interpreter No Such File or Directory Error?
To fix the bin bash m bad interpreter no such file or directory error, ensure that the shebang line in the Bash script is correct and points to the correct location of the Bash interpreter. The script file should exist in the specified location with the appropriate file permissions.
If the error persists, try moving the script file to a different location and check for any possible file system issues.
– Check the Shebang Line
Ensure that the shebang line in the script is correct and specifies the correct path to the interpreter. For example, if the script is a Bash script, the shebang line should be #!/bin/bash. If the path is incorrect, update it to the correct path for the interpreter.
– Check the Interpreter
Check if the interpreter specified in the shebang line exists in the system and is executable. Use the which command to check if the interpreter is installed and in the PATH. For example, “which python” will show the path to the Python interpreter. If it’s not installed, install it using the package manager for your operating system.
– Check File Encoding and Line Endings
Ensure that the script file has the correct encoding and line endings. If the script was created on a Windows system, it might have Windows-style line endings (CRLF) which are incompatible with Unix-style line endings (LF). Use a text editor that can convert line endings, such as dos2unix, to fix the line endings.
– Check File Permissions
Ensure that the script file has the execute permission. Use the chmod command to add the execute permission to the file. For example, “chmod +x script.sh” will make the script file executable.
– Check for Dependencies
Check if the script has any dependencies that may be missing or not installed. If there are dependencies, install them using the package manager for your operating system. When a script or program is executed, other software packages or libraries may be installed to function properly. These packages or libraries are called dependencies.
If a required dependency is missing or not installed, it can cause errors or prevent the script from running correctly. To check for dependencies, you can usually review the documentation for the script or program to see what requirements are needed. The documentation may list the required packages or libraries and their versions.
Another way to check for dependencies is to examine the script or program code itself. It may contain import statements or other commands referencing specific modules or libraries. These can be used to identify what dependencies are needed.
Once you have identified the dependencies, you can use the package manager for your operating system to install them. For example, on a Linux system, you can use the apt-get, or yum command to install packages. On a Mac, you can use Homebrew or MacPorts to install packages.
– Copy the Script to a New File
Copying a script to a new file is a troubleshooting step that can help resolve file encoding or corruption issues. When a script is saved or transferred between different systems, it can sometimes encounter issues that affect its ability to execute correctly. By copying the script to a new file, you can create a fresh copy that is free from any such issues.
Here are the steps to copy a script to a new file:
- Open the original script file in a text editor.
- Select all the contents of the file using the Select All command or shortcut (such as Ctrl+A or Cmd+A).
- Copy the selected contents to the clipboard using the Copy command or shortcut (such as Ctrl+C or Cmd+C).
- Create a new empty file in the same directory or location as the original script file. You can do this by selecting file> New or by using the appropriate shortcut.
- Paste the copied contents of the original script into the new file using the Paste command or shortcut (such as Ctrl+V or Cmd+V).
- Save the new file with a new name and the correct file extension for the type of script. For example, if the original script file was named script.txt, and it was a Bash script, you might save the new file as a script.sh.
By creating a new file and copying the contents of the original script into it, you can ensure that the file is free from any issues that may have affected the original file. If the original file was corrupted or had encoding issues, the new file should be free from these problems and be able to execute correctly.
– Syntax Errors
Syntax errors can manifest in different ways, depending on the programming language used and the type of error. For example, a syntax error may appear in Bash scripts as a “syntax error near unexpected token” message. At the same time, in Python, it may show a “SyntaxError” message with details about the error.
To resolve syntax errors, you need to review the code and correct any errors that are found. The exact steps to correct syntax errors depend on the specific error and programming language used. By solving syntax errors, you can remove some other error messages, such as:
- /bin/bash^m bad interpreter no such file or directory centos 7.
- /bin/bash^m bad interpreter no such file or directory vscode.
- /bin/bash^m bad interpreter no such file or directory intellij.
- Bin/bash: no such file or directory.
Conclusion
Now that you have read this article completely, you will be able to resolve this error on your own with a proper understanding of why this error occurs and how you can resolve it. Let’s see some major points:
- The “bad interpreter” error in the Bash shell typically occurs when the specified interpreter cannot exist or be found.
- This error message often indicates a problem with the file path or permissions and a missing or incorrectly installed interpreter.
- To troubleshoot this error, you should first check that the interpreter path is correct and exists on the system.
- You can also try reinstalling the interpreter or checking its permissions to ensure that it is executable.
- Other possible causes of this error include file corruption or incompatibility with the operating system.
We are confident that at this stage, you can overcome this challenge on your own.
