Cut output of shell with starts and finishes specific character

I have a html/text file which has downloadable URL of video but I need to cut the file as link.

For example, it starts with url240= or url360= or 480 etc. and there is URL LinkOfUrl and finishes with &jpg...

I want to get output like url240=https://cs542402.vk.me/6/u313752528/videos/68ec547387.240.mp4?extra=JVSeMzU2-msXVuseackTFCgnVNEPOnboxMdXN3ZGH1l91djR7bk9DzaxyKFGJ2SXg39BcZxJM6tBip0ui3dDEkULDSbkuzpaOA or this is my point -->> https://cs542402.vk.me/6/u313752528/videos/68ec547387.240.mp4?extra=JVSeMzU2-msXVuseackTFCgnVNEPOnboxMdXN3ZGH1l91djR7bk9DzaxyKFGJ2SXg39BcZxJM6tBip0ui3dDEkULDSbkuzpaOA

How can I do?

My aim is that grabbing video link and downloading it from terminal not using browser or not using manually entires. I am planning to write a shell script to do it automatically so I need to assign link as variable after that I will use axel $variable . (I used wget to get html/text files if anyone wondered it how I get.)

Here is my original html/text file

There is small text of file which I have :

Solution

This should give you some ideas...

sed 's/&amp;/\n/g' | grep url240 | cut -d= -f2

separate parameters joined by "&", grep the required line, get the right handside of the = sign.

If you have = sign in the contents, just cut based on the variable name length. For example

var="url240"; sed 's/&amp;/\n/g' | grep $var | cut -c $((${#var}+2))-
