Executing script from shell problem

rated 0 times [ 10] [ 0] / answers: 1 / hits: 14866 / 2 Years ago, mon, march 28, 2022, 2:17:41

Lubuntu Raring Ringtail. I want to be able to execute my scripts with ./

I start my python script with #!/usr/bin/python and it says

bash : ./myscript.py: /usr/bin/python^M: bad interpreter: No such file or directory

If I use #!/usr/bin/env python it gives a similar error:

: No such file or directory

What am I doing wrong?

I absolutely have python installed, and can run the scripts as normal with python myscript.py

From the ^M you can see that the file myscript.py is using windows/dos-style line breaks (Windows uses CR LF (carriage return + line feed) at the end of a line. Unix only uses LF - so what you see as ^M is the CR. So what you are not using /usr/bin/python but /usr/bin/python<CR> that does not exist.

You can remove the ^M using dos2unix (do a sudo apt-get install dos2unix to install and then use dos2unix myscript.py).
