Linux: Block until a string is matched in a file (“tail + grep with blocking”)

Question

Is there some one-line way in bash/GNU tools to block until there\'s a string matched in a file? Ideally, with timeout. I want to avoid multi-line loop.

Answer 1

tail -f file | grep word | head -n1

Will post snip with async timeout

The linked answer defines a 'run_or_timeout' function that does what you are looking for in a very bash-savvy way
