Is there a clean Windows port / version of the /usr/bin/time command in Linux (program to time the execution of a process)?

  • What feature of `/usr/bin/time` are you looking for on Windows, specifically? – EvilChookie Aug 28 '09 at 00:49
  • The ability to time my programs of course. – unknown Aug 28 '09 at 00:53

    Your question assumes that people know what `time` actually does on Linux. Someone may not use Linux, but may know a Windows Alternative to what you're looking for (which is the ultimate goal of your question) - it would be helpful for those people to state what you're looking to achieve. – EvilChookie Aug 28 '09 at 01:40
  • I agree with EvilChookie. +1 now that I understand what you want. – Sasha Chedygov Aug 28 '09 at 03:15
  • Please see my answer for a link to `timethis.exe` which does what you want and is available as an approx 116K download. – Sinan Ünür Aug 28 '09 at 03:21

I have created a simple Windows program called timemem.exe that behaves similarly to /usr/bin/time on Linux/Mac OS X, and will show similar statistics, such as elapsed time, user and kernel CPU time, and maximum working set size in memory used by another Win32 process. See:

If you want time to use it as a benchmark utility, the Windows 2003 Resource Kit has Timeit.exe which does the same.

  • Cool, can I get it without getting everything else there? – unknown Aug 28 '09 at 00:44
  • Unfortunately that seems to be the only download Microsoft provides. But there are a lot of useful tools in there which I have renamed to their UNIX equivalent and dropped into my System32 folder for use from the command line. You can simply delete the ones which you don't want. – John T Aug 28 '09 at 00:50
  • John T, congrats on being first to 10k! Enjoy reading your posts... Don't know how you find the time as every time I am about to submit, you seem to have the same / slightly better answer! Here's to the next 10k!- Delete this after you have read it as there is no private message feature! (or write another commend then il delete it) – William Hilsum Aug 28 '09 at 01:59
  • @Wil, thanks! I cannot delete it and there is no need to. Comments are exactly that, comments. Good ones are rather appreciated :) – John T Aug 28 '09 at 05:18

Use timethis from the Win2K resource kit.

A bit late to the party, but I was searching for a Windows version of /usr/bin/time. Could not find anything, so I wrote a clone:

https://github.com/cbielow/wintime

It can measure

  • execution time of a program
  • RAM usage (maximum)
  • page faults etc...

including logging to a CSV file. Precompiled binaries are available. Just download and run it.

You could always install Cygwin which will give you the UNIX time command. It is pretty useful to have Cygwin installed anyway.

By you asking for a clean port or version, I don't think Cygwin would be acceptable. The only thing I have found is this for custom code to compile on Windows. As I didn't find any links where this has been set up as the time command, I don't know that you could get this to work unless you wanted to program it yourself.

On my Mac, /usr/bin/time returns the system uptime.

On a Windows computer, you can use the following to return the uptime: net stats server

The 'Statistics Since' will give you the time the computer was last powered up. There's also a server tool - uptime.exe

There's more information at the Microsoft Support Site.

Of course, if you're not looking to find the uptime of a computer, I'm way off the mark. If you're not looking for uptime, what are you looking to achieve?

Edit: If you're looking for CPU time as suggested in a comment, you can use the tasklist command. Punch in tasklist /? at a command prompt and see the info about it.

PowerShell already has the built-in capability to measure runtime with the cmdlet Measure-Command

Measure-Command { Get-EventLog "windows powershell" }

Of course it can also be called from cmd or any applications

powershell -C "Measure-Command { sleep 2 }"
