Please follow the ideas of Xiaobian slowly and deeply to study and learn "how to solve the problem of bash: /usr/bin/autocracker: /usr/bin/python^M: bad interpreter: No such file or directory" together!

Python script written under windows system, after granting permission chmod +x xxx.py under linux, execute./ xxx.py run instructions: bash: /usr/bin/autocritter: /usr/bin/python^M: bad interpreter: No such file or directory

Analysis:

This is caused by different system encoding formats: .sh .py files edited on Windows may have invisible characters, so executing them on Linux will report the above exception message. This is usually due to the difference in the end-of-line identifier between windows and linux.

Solution:

1) Convert under Windows:

Use tools such as UltraEdit or EditPlus to encode scripts before putting them into Linux for execution. The conversion method is as follows (UltraEdit): File--> Convertions-->DOS->UNIX.

2) Direct replacement under Linux:

sed -i 's/^M//g' filename (note ^M is written in Linux press ^M for carriage return, input method is hold down CTRL+v, release v, press m)

3) It can also be converted in Linux:

First, make sure the file has executable permissions

The code is as follows:

#sh>chmod a+x filename

Then modify the file format

The code is as follows:

#sh>vi filename

Use the following command to view file formats

:set ff or:set fileformat

You can see the following information

fileformat=dos or fileformat=unix

Modify the file format using the following command

:set ff=unix or:set fileformat=unix

:wq (save exit)

Final execution file

#sh>./ filename
