Fish has smoother usability, autocompletion and search. It is useful on fresh machine in vanilla configuration. Installing bash plugins is not always possible.

Fish has smoother usability, autocompletion and search. It is useful on fresh machine in vanilla configuration. Installing bash plugins is not always possible. Installing some sync plugin on sensitive server is nono! Also my biggest problem with bash, sometimes it does not keep part of recent history, if bash process gets killed. Fish does not have this problem. I usually keep useful commands in notes, and sync my notes instead.
