Permission denied when launch python script via bash

Question

# ./scripts/replace-md5sums.py
bash: ./scripts/replace-md5sums.py: Permission denied

replace-md5sums.py has chmod 600

# ls -l ./scripts/replace-md5sums.py
-rw------- 1 ubuntu ubuntu 661 2011-04-27 16:30 ./scripts/replace-md5sums.py

Do `ls -l /scripts/replace-md5sums.py` and past the results in your question. — S.Lott, Apr 27 '11 at 17:04
"replace-md5sums.py has chmod 777" is false. Please remove it from the question. — S.Lott, Apr 27 '11 at 18:02
does the scripts directory have the x rights for your user ? (something like this in the output of `ls -l` `drwx r-x r-x`) — Cédric Julien, Apr 27 '11 at 16:58
# ls -l ../ total 4 drwx------ 1 ubuntu ubuntu 4096 2011-04-27 16:42 meta-doctor — r9s, Apr 27 '11 at 16:59
@r9s: Do `ls -l /scripts/replace-md5sums.py` and past the results in your question. Not in a comment. In the question. Properly formatted so we can read it. — S.Lott, Apr 27 '11 at 17:05
try a `chmod 711 scripts` to completely exclude rights problems — Cédric Julien, Apr 27 '11 at 17:04
I'm root on Ubuntu LiveCD and that script is on windows partition. — r9s, Apr 27 '11 at 17:03

You should be able to run the script typing:

$ chmod 755 ./scripts/replace-md5sums.py
$ ./scripts/replace-md5sums.py

There are times where the user you are currently logged with just don't have the permission to change file mode bits. In such cases if you have the root password you can change the file permission this way:

$ sudo chmod 755 ./scripts/replace-md5sums.py

If you don't like to give the `x` flag you can use 744. Here to run the script you have to type `python ./scripts/replace-md5sums.py` explicitly. – Paolo Apr 28 '11 at 17:06

In the terminal enter: chmod u+x script name with the '.py' extension in the end.
Remember, u stands for user and x read, write and execute actions to the file.
Keep in mind as well the line which must go on top of your Python script which is: #!/usr/bin/python3.9 Going on root you can easily identify what the python version and path is.
Now re-execute it again.

Mount your Windows partition with "exec" option - on some distros it's "noexec" by default.

I had the same problem with my XFS partition. – Fabien R Oct 23 '13 at 15:35

I solved my problem. it's just the version of python which the interpreter reads off the first line. removing to version numbers did it for me, i.e.

#!/usr/bin/python2.7 --> #!/usr/bin/python

I'm a Ubuntu user and I had the same issue, when I was trying to run python script through a bash script while files were located in a NTFS partition (even with su didn't work) then I've moved it home (ext4) then it worked.

Okay, so first of all check if you are in the correct directory where your python script is located.
On the net, they say to run the command :

python3 your_file_name.py

But it doesn't work.
What worked for me however was:

python -u my_file_name.py

Check for id. It may have root permissions.

So type su and then execute the script as ./scripts/replace-md5sums.py.

It works.
