> NO_OF_FILES=`ls ${DIRECTORY}/*.eps|wc -l`

Uses two child processes, more efficient to save the list of files into an array, then look at the length of the array:

files=($directory/*.eps)
no_of_files=${#files[*]}

You CAN use test if you want Bourne shell syntax, or you can:

if (( $no_of_files > 0 ))
then
   # do stuff
fi
