[SOLVED] How to grep -v/--invert-match based on content of file?

Issue

I'm running a bash commando to filter a file using grep, awk and xargs, and I'm happy with the output I'm getting, however I would also like to exclude some lines based on content of an existing file.

E.g

My output

IP1 HostX1
IP2 HostY2
IP3 HostY3
IP4 HostY4
IP5 HostY5
IP6 HostY6
IP7 HostX7

I want to be able to include grep -v based on entire content of a file, e.g diff ... | awk ... | xargs ... | grep -v FILE The FILE looks like:

IP2 HostY2
IP3 HostY3
IP4 HostY4
IP5 HostY5
IP6 HostY6

Desired output

IP1 HostX1
IP7 HostX7

Solution

I solved it adding following: commands ... | grep -v -f FILE
