I'm trying to extract fields from a pipe-delimited file and provide them as arguments to an external program in a loop. The file contains lines like this:

value1|value2
value3|value4

So I came up with:

 while read line;

    do echo -n "${line}" | awk -F '|' '{print $1}';
       echo -n " something ";
       echo -n "${line}" | awk -F '|' '{print $2}';
       echo " somethingelse";

 done < <(cat $FILE)

I want to see the following output:

value1 something value2 somethingelse
value3 something value4 somethingelse

But instead I'm getting:

value1 
 something value2
 somethingelse
value3
 something value4
 somethingelse

Perhaps I shouldn't be using echo?
