By default, direnv will output messages every time it enters and leaves a directory with a .envrc file in it. To make direnv quiet down and not output these messages, you can set the DIRENV_LOG_FORMAT environment variable to an empty string, like this:

# make `direnv` silent
export DIRENV_LOG_FORMAT=

Alternatively, you can tell direnv to display these messages in a “faint” color:

export DIRENV_LOG_FORMAT=$'\033[2mdirenv: %s\033[0m'

See this blog post for more details on this approach.
