IRB provides an autocomplete feature today. It’s really great but since it makes full use of escape sequences, sometimes could cause trouble when sharing a terminal with others over the internet (using Visual Studio Code Live Share, tmate, or some such).

Today I learned that the autocomplete feature can be disabled temporarily by passing --noautocomplete option.

irb:

irb --noautocomplete

bin/rails console:

bin/rails c -- --noautocomplete
