Current version of exa package installs the completions into /share/bash_completions/completions/exa while all other bash completions are in /usr/share/bash-completion/completions/.
The exa completions are not loaded with current path, e.g. I try exa -s [tab] [tab] I don't get the expected search options listed, but the folder content. When I copy the exa completions file into /usr/share/bash-completion/completions/, it works as expected.
