I can't seem to get the verbose mode of time working. I am trying to compare the compute cost of sha256-crypt to sha512-crypt: time doveadm pw -s sha256-crypt -p secret real 0m0.128s user 0m0.081s sys 0m0.040s time doveadm pw -s sha512-crypt -p secret real 0m0.162s user 0m0.105s sys 0m0.047s But all attempts to add --verbose fail: time --verbose doveadm pw -s sha512-crypt -p secret -bash: --verbose: command not found Googling gives different recommendations, none work for me.
