[IPython-user] ls and cat commands fail

[Tony Mannucci]

I am running ipython 0.8.4 on Mac OS X 10.4.11 (PowerPC). Python 
version 2.5. I am having trouble with ls and cat commands. These work 
on other installations I have access to. The error message looks like:

>[python/source]|3> cat junk.dat
>---------------------------------------------------------------------------
>NameError                                 Traceback (most recent call last)

Thanks for your help!

I did not have this problem on ipython 0.8.2.
