When we need to search history in bash but multi command same pattern, you must type difference longest chain of result you want.
Example, my history bellow:
$ history ssh srv-local-1 ssh srv-local-2 ssh srv-local-6 ping google.com telnet srv-local-1 ssh srv-partner-1 ping srv-partner-6 ssh srv-partner-6
So, when I want retrieve command
ssh srv-partner-6 I use control (^) + r (in macos) maybe I type (as short as possible):
ping (because latest command used match pattern).
But when retrieve command
ssh srv-local-1 you maybe type ssh with enter control + r multi time.
But when modify bind key control + r to history-incremental-pattern-search-backward you only need type intermittently different word by use regex.
echo "bindkey '^R' history-incremental-pattern-search-backward" >> ~/.zshrc source ~/.zshrc
Now we can search
ssh srv-local-1 by type:
~ ssh srv-local-1 bck-i-search: ssh*l*1_
