Problem with Mathematica in batch mode.

I'm trying to run mathematica in batch mode on a UNIX box. If the output
appears on two lines, as it does on occasions, the results are wrong.
Any help appreciated.

The following puts a set of commands in the file foo, and writes the
result to the file foobar, it works fine.

sparrow /tmp % echo "1+2" > foo
sparrow /tmp % math -batchinput -batchoutput < foo > foobar
sparrow /tmp % cat foobar
" Cannot initialize Motif graphics "

3

But here is an example of where it goes wrong. In this case the number
has a power, which gets put on another line, which is not directed into
the file.

sparrow /tmp % echo "10000000000000+2.043" > foo
sparrow /tmp % math -batchinput -batchoutput < foo > foobar
sparrow /tmp % more foobar
" Cannot initialize Motif graphics "

1.0000000000002043*^13

In this case, Mathematica would normally show 1.0000000000002043*10^13,
but the "10" appears on the line above and so gets missed.
