Simple Bash issue, but I can't figure it out!

Hey all,

I'm working on a bash script that reads data from a file using cut. I have the whole thing working just like I want, except that my while loop never terminates! Apparently I don't know what to compare it to if my 'cut' statement exceeds its available data. If I do

echo `cut -s -d, -f 7 file`

and my file only has 6 fields, I get a blank space. What can I compare to the output of cut in this case, so that when it no longer has data (my field counter exceeds the number of available fields), the loop will terminate?

Ok, finally found the problem.

cut -s -d, -f X

is wrong in this case...

cut -d, -f X

works fine! The while then compares the variable where the results of the above cut statement are stored like so:

while [ -n $VARIABLE ]; do ...

And my infinite loop is gone!
