You can 'grep "^line$" "filename"' and check the variable "$?". If it
is 0, there is the line. If 1, there isn't. The script maybe like,
line1 = "any line"
line2 = "another line"
for i in *; do
grep "^$line1$" $i;
if [ x$? = x1 ]; then
echo $line1 >> $i;
grep "^$line2$" $i;
if [ x$? = x1]; then
echo $line2 >> $i;
fi
fi
done
