Fgrep -v

Using the fgrep command with the -v option.
I have two files:
Code:
file1:
dog 1
cat 3
bird 5
fish 7

Code:
file2:
dog
cat

Using
Code:
fgrep -v file2 file1

According to the fgrep man page, the output should be
Code:
bird5
fish 7

but I can't seem to get it to work. Any help would be appreciated.
# 2  
You need to specify the -f option to make file2 the pattern file:
Code:
fgrep -vf file2 file1
bird 5
fish 7
