How to run executable with Python code inside

Question

I have the following file:

$ cat my_exec.sh 
#!/usr/bin/env python
print(10)

It should just print 10. However, I can't get it to do so:

$ sudo ./my_exec.sh
sudo: ./my_exec.sh: command not found
$ sh my_exec.sh 
my_exec.sh: line 3: syntax error near unexpected token `10'
my_exec.sh: line 3: `print(10)'

How do I run my file?

• Alan Kavanagh: Rename your script to my_exec.py and update the first line to #!/usr/bin/python
• Aaron: sudo means "super user do". Do you need your script to be executed with elevated/different permissions? If not, don't use sudo. sh executes a shell script in POSIX-compliance mode, so you don't want that either. Have you tried ./my_exec.sh ?
• Sahand: I did sudo because simply doing ./my_exec.sh resulted in permission denied.

Answer 1

You can run it via the python command:

$ python my_exec.sh

To run it as simply ./my_exec.sh, you need to make the file executable first:

$ chmod 755 my_exec.sh

Also note that by convention python files end in .py .

Answer 2

• Change the shebang to #!/usr/bin/env python
• Change the filename to my_exec.py, as is convention for python files
• You can run with python my_exec.py
• You can chmod +x my_exec.py and then ./my_exec.py

Answer 3

You must enter the directory that you have saved you file through the cmd with cd command. After that you just execute the file with : python name_of_the_file.py . But first you must make it executable with chmod command

For example if you have saved your file at Desktop with the name mycode.py :

cd Desktop
chmod +x mycode.py
python mycode.py
