How to remove brackets from all output lines?

Question

bash

There is a file with the list of hosts. Using the fping command, I get the result in the form:
host1 is alive (30 ms)
host2 is alive (22 ms)
How can I remove these brackets from the output? Next, I can sort the hosts by ping time with sort -nk4.
upd: I will add an explanation: the result should be in the form host1 is alive 30 ms

Answer 1

$ echo 'host1 is alive (30 ms)' | tr -d '()'
host1 is alive 30 ms

Answer 2

You are apparently doing: fping -aeg
you need to: fping -ag
