You can do something like this:

grep --only-matching -P "http.*?\.(pdf|doc)" myfile.pdf

The output for your sample is:

https://website.com/BTAE/2015/BTAE assignment jan 15.pdf
https://webservices.ignou.ac.in/assignments/BTAE/2015/BTAE assignment jan 15.pdf
https://website.com/BTAE/2015/base-005.pdf

@AabirHussain That is because the URL is not prefixed with http – fejyesynb – 2018-09-05T03:41:17.780
