Whenever I try to use options with the time command, such as format (-f, --FORMAT), I get the following error:
bash: -f: command not found
How do I use options with time?
You are invoking the bash's built-in version of time, which has slightly different behavior and options – described in bash's manual as well as help time.
Use command time ... to bypass the built-in and execute the external command; or run /usr/bin/time ... directly.
command time ...
type -a time
