This command would cause a deadlock and make fzf crash: fzf --bind 'start:reload:ls' --height ~100% Because, 1. 'start' event is handled by Terminal 2. When 'reload' is bound to 'start', fzf avoids starting the initial reader 3. Terminal waits for the initial input to find the right height when adaptive height is used 4. Because the initial reader is not started, Terminal never gets the initial list 5. No chance to trigger 'start:reload', hence deadlock This commit fixes the above problem by extracting the reload command bound to 'start' event and starting the initial reader with that command instead of letting Terminal start it. This commit also makes the environment variables available to $FZF_DEFAULT_COMMAND. FZF_DEFAULT_COMMAND='echo $FZF_QUERY' fzf --query foo Fix #3944
