If Bash is your default shell, you can install Fish to try its superb auto suggestions and the tab key, while leaving Bash as your default shell. These auto suggestions do not only work for your command line history but also for file names even when your first letters you type are in different order in the file name (For example, I know that I want to edit a file with the word work in it and start typing the word work and press tab key, but it turns out that the word does start instead with the word personal, Fish is still able to suggest the real file name to edit : personal_and_work_todo.txt). Fish has saved me a lot of typing time. And if you need Bash for a moment (Fish will complain about certain * usage), then temporarily exiting Fish or typing bash is an option.

After installing Fish, run the fish_config command to configure it via a local session in your web browser.
