How to make wget and multiple grep variants?

Question

linux

Good afternoon,
There is a command on the tower:

wget -T 2 -t 1 --no-dns-cache --max-redirect=0 --spider customurl 2>&1 | grep 'application/zip'
        if [ $? = "0" ];
...

If the file exists, it starts downloading.
Is it possible to somehow specify grep 'application/zip' or grep 'application/x-gzip'

Answer 1

either split into 2 queries, or grep 'application/zip | application/x-gzip'

Answer 2

grep -E 'application/(xg)?zip'
