For a simple example say I have list file which has the following contents

cat dog pig

dog hat

cat

clap sing

king

ca

cat hog

plate

plate

one two three

cat

I then have a 'pattern' file. With the below content

cat 

dog

What I would like to happen is a new file is created from the list file but all lines that begin with cat or dog I not copied over.

I have seen a few examples how this can work e.g.

sed '/pattern to match/d' ./infile > ./newfile

From what I have gathered sed can't handle a 'pattern input file'. Is that a similar program to sed that could achieve what I would like to do? If not could a make a program in python program that reads each line from the 'pattern' file and run the sed command against th list file e.g. multiple passes with seds
