To install GNU time in OSX?

Question

BSD time gives this kind of output

9990

real    0m4.371s
user    0m1.548s
sys 0m2.167s

GNU time gives then again this kind of output

9990
1.56s user 1.46s system 82% cpu 3.648 total

Brew search gtime gives nothing. GNU time is probably in some C library, however, I am not sure which. There is no apparent package for it.

How can you install GNU time in OSX?

Using /usr/bin/time gives me the results that you want. time by itself with a command is a shell keyword. — fd0, Jul 01 '15 at 20:40
@fd0 I do not get such an output. My time is also in usr/bin/time. My time version is BSD 1993. You must have different version of time. — Léo Léopold Hertz 준영, Jul 01 '15 at 20:44
time date vs /usr/bin/time date produce 2 different outputs (like your examples above). But which time gives /usr/bin/time. — CousinCocaine, Jul 01 '15 at 20:51
@Masi the time man page states BSD June 6, 1993. I have no idea why your results are different. — fd0, Jul 01 '15 at 21:11

I think what you are looking for is available as...

brew install gnu-time

Which you can then call as...

gtime ...

you just beat me to it. https://gist.github.com/gregelin/9529716 – CousinCocaine Jul 01 '15 at 20:54
No manuals installed by this in gtime. How can you get manuals also with this command? I would like to get more significant numbers in timing. – Léo Léopold Hertz 준영 Jul 06 '15 at 08:39

The original package from GNU doesn't appear to have a man page. However it does have an info file you can find with info time. – Alistair McMillan Jul 07 '15 at 07:38

@LéoLéopoldHertz준영 here's an online version of the man page – Dennis Feb 03 '17 at 17:53

If you want to call it as time, then install it as brew install gnu-time --with-default-names. Your original installation of bsd-time will still exist, but gnu-time will be executed by default as it appears in your PATH first. – Dennis Feb 03 '17 at 17:57
