Linux Command: How to print all URL from file - grep url from file linux

grep all http urls - grep url from file - grep url regex

Scenario

I have one sitemap.xml file that is too big and in this sitemap.xml file have http/https url something like this

I need all those url for submitting for review and approval by indexnow tools

Challenges: 

We don't know how many url's exist on this sitemap.xml file and manually activity will take a lot of time also could be change of human error.

Solution: 

Grep command can help me on this situation, ( Let me comment if we can do this via any other option ) 

Here,  I have window Operation System with installed mobaxterm ssh manage and I'm using local terminal on it so let's try  

 

1 - I have downloaded the sitemap.xml file

curl https://www.linuxtopic.com/sitemap.xml -o /tmp/sitemap.xml

2 - Once download, use below grep command to print all the http URLs

grep -o -E "https?://[][[:alnum:]._~:/?#@&'()*+,;%=-]+" /tmp/sitemap.xml
OR
grep -Eo "(http|https)://[a-zA-Z0-9./?=_%:-]*" /tmp/sitemap.xml

So, I got all the URLs and submitted for review.
