Hi I have wrote a script for a webpage in python. However when I run it I seem to get this error

/usr/bin/env: python\r: No such file or directory
Premature end of script headers: users.cgi

I'm not sure what is causing it, so far I have:

  • A Shebang which is #!/usr/bin/env python
  • I also have other scripts that execute fine on the same server in the folder.
  • I have no syntax errors in the code (I've used IDLE to check)
  • The file also has 755 permissions and is owned by www-data

Could someone help me or point me in the right direction. I can't work out what is going wrong. There is very little in the apache error log. Your help will be greatly appreciated

You've uploaded the file with DOS/Windows line endings. UNIX script executables have to be saved with UNIX line endings.

I thought that might have happened is that what the /r was? How do I change this so that it will work? – Riley May 29 '14 at 17:56
    
Right, that's what the \r is — it's part of the DOS/Windows line endings. (You're lucky that env outputs it this way; in some situations, it'll show up as a literal carriage return, which is much more confusing.) Check your text editor settings for how to fix it, or run dos2unix on the server. – duskwuff May 29 '14 at 18:20
    
If you are using a text editor to write your scripts, I recommend notepad ++ (notepad-plus-plus.org) as it is developer oriented. – NuclearPeon Jun 30 '14 at 23:33
