This is my list of sed commands: can anyone tell me where im going wrong. The script works on a file called data which contains 6 student id's and there answers for 6 questions.

!/bin/sh
sed -e 's/*//g' \ #replace * with nothing
-e s/ /X/g' \ #replacing empty space with X
-e 's/960...../& \ #student No.
/g' \
-e 's/[0-9][0-9][TFX][TFX][TFX][TFX]/&\
/g \
e 's/[TFX]/ &/g' \

When it outputs the file there is an extra line with nothing on it. How do i get rid of the extra line??
e.g.
52000012
01 8
02 4
03 8
04 2
05 0
06 6

52000013
01 8
02 4
03 10

Any suggestions would be greatfully recieved.

Your error appears to be here my firend.

-e 's/[0-9][0-9][TFX][TFX][TFX][TFX]/&\
/g \

Simply swap it for this and I believe it will work...

-e 's/[0-9][0-9][TFX][TFX][TFX][TFX]/\
&/g \

Pretty simple really...
But in future I suggest you dont post your university assignments on notice boards. Their assigned to you and only you!
