One way to break a huge logic statement like that into several smaller ones is:

Code:
while read filename
do
        REMOVE=0

        if [ ! condition1 ]
        then
                REMOVE=1
        fi


        if [ ! condition2 ]
        then
                REMOVE=1
        fi


        if [ ! condition3 ]
        then
                REMOVE=1
        fi

        if [ "$REMOVE" -eq 1 ]
        then
                remove_filename
        fi
done
