sed '/^[ ]*$/ d' $file > /tmp/tmp1
set field = 'head -1 /tmp/tmp1'

IMHO the first sed line deletes all the lines from $file where the line is empty (only contains a newline character) or is filled with spaces.
The next line sets the field variable to the first non empty line of the original $file.
But from my point of view it should be written as
set field=`head -1 /tmp/tmp1`

HTH
