How to get part of string after some word with Ruby?

Question

I have a string containing a path:

/var/www/project/data/path/to/file.mp3

I need to get the substring starting with '/data' and delete all before it. So, I need to get only /data/path/to/file.mp3.

What would be the fastest solution?

Answer 1

'/var/www/project/data/path/to/file.mp3'.match(/\/data.*/)[0]
=> "/data/path/to/file.mp3"

Answer 2

could be as easy as:

string = '/var/www/project/data/path/to/file.mp3'

path = string[/\/data.*/]

puts path
=> /data/path/to/file.mp3
