grep -v -f abc.txt    -v inverses the matching of patterns in the
-f abc.txt file.

so if echo "3.g" > abc.txt  would find and delete all *.gif files in XXX
except those files containing string "3.g" regardless of prefix.  

find XXX YYY -iname "*.gif"  finds all files in folder XXX and YYY in
upper or lowercase.
