VIM : Deleting all characters before particular word for all the lines in a file

Question

I need a vim command for deleting all characters before a particular word for all the lines in a file

Ex: Input:

asdfasdfasdfscccHello

qwerqwerHello

24351243vsfgertHello

Output:

Hello

Hello

Hello

Answer 1

If you want to delete all characters before "Hello", you can do

:%s/.*Hello/Hello/

Note that .* is greedy, i.e. it will eat all occurrences of "Hello" till it finds the last one. If you have a line:

abcHellodefHelloghi

it will become

Helloghi

If you want a non-greedy solution, try

:%s/.\{-}Hello/Hello
