Yep this fixes it! much better than my solution of writing it to a file and then executing it XD. How can I change it to execute through Bash by default?

    os.execute'bash -c "echo -n text ... "'

or link /bin/sh to /bin/bash, which makes it permanent.

When I run this command in my Bash shell, the output I get is "-n text". Is this a bug or am I messing up something simple? I've never encountered this problem with os.execute before .

Most likely the shell used to evaluate the parameters to the system() call does not support the -n option. Try:

   /bin/sh -c ‘echo -n “text”'


   /bin/bash -c ‘echo -n “text”’

I get “-n text” as output to the first command and “text” to the second.

On most systems Lua will had the os.execute() parameter to /bin/sh for processing as that is the behavior of the system() call.
