If you want to ensure you're running the command, use command, if you want to ensure you're running the builtin, use builtin. There's no magic here. Use help to figure out the commands available or type <command> to figure out what type <command> is (e.g. a builtin, external command, function or alias).

Basile, you are quite right. I hadn't spotted the significance of the command command. Which is fact ensures that /usr/bin/time is called. This means that the following two statements are compatible: $ command time -f %e sleep 4 and $ /usr/bin/time -f %e sleep
