Shell Programming and Scripting

Hello,

I want to search a word inside a file from a script, that is moving through a script line by line and when I find the word "hello" to cut all the text from the beginning to there and so many times successively to get the word "hello "until the end of the text. Ie if a 4 times to cut the text 5 times since the last part there will be no text.

Thank you very much
