#SSH Config File Match Example
The Host directive can contain one pattern or a whitespace-separated list of patterns.
Each pattern can contain zero or more non-whitespace character or one of the following pattern specifiers:* - Matches zero or more characters. For example, Host * matches all hosts, while 192.168.8.* matches hosts in the 192.168.8.0/24 subnet.
? - Matches exactly one character. The pattern, Host 10.10.8.? matches all hosts in 10.10.8.[0-9] range.
! - When used at the start of a pattern, it negates the match.
Host * !fm means all hosts except fm
Host * !fm ProxyJump fm Host * # Does not use ProxyJump here
