# Sage in console: newline characters?

I like to use sage in a linux console, rather than the notebook interface, simply for speed and convenience. However, I have problems if I want to edit a multi-line statement. For example, suppose I enter:

```
for i in range(10):
if is_prime(i):
print i
```

If I want to edit this, or maybe just run it again, when I call it up with the history mechanism, what I see is

```
for i in range(10):^J if is prime(i):^J print i
```

This can be very inconvenient if there are lots of short lines. (I can get round this by running sage within GNU screen.) I'm not quite sure how I encourage newlines to be interpreted as, well new lines rather than newline characters, and whether this is a sage, ipython, or console issue.

You may want to try `%edit`, an ipython magic function which allows this kind of editing.

What is weird is that ipython 0.13.1 (not the one shipped sage, but same version) has the right behaviour.

What platform is this? I wonder if this is the bug reported at http://trac.sagemath.org/sage_trac/ticket/14405.

I'm using Sage 5.2 on Ubuntu 12.04. I've not had this problem with previous versions of Sage. It does seem to be the problem referred to above. I have (for my distro) the most up-to-date versions of libncurses and libncurses-dev.
