Bash and Nginx - how to find URLs without redirects?

Question

bash

Good day!
Actually, subject. Approximate algorithm: on the server in access.log, you need to find lines with HTTP headers not equal to 301 and 302 (that is, URLs without redirection) and display them on the screen.
Something like:
cat access.log | grep [!= 301 || !=302]
The fact is that I am familiar with bash at a basic level and, to be honest, I have little idea how to make this script.Thanks
in advance!

Answer 1

cat access.log | egrep -v "301|302"
