time - measure how long a command or block takes¶
time causes fish to measure how long a command takes and print the results afterwards. The command can be a simple fish command or a block. The results can not currently be redirected.
For checking timing after a command has completed, check $CMD_DURATION.
Your system most likely also has a
time command. To use that use something like
command time, as in
command time sleep 10. Because it's not inside fish, it won't have access to fish functions and won't be able to time blocks and such.
(for obvious reasons exact results will vary on your system)

Inline variable assignments need to follow the
