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

Answer 1

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

Answer 2

Do chmod +x script

Now try executing.
