Where are the EXEs for Subsystem For Unix Applications so I can use it?

Question

I am on Windows 7 Ultimate.

I have done done start..ctrl panel..programs..turn windows features on and off...and ticked Subsystem For Unix Applications

enter image description here

When I click the start menu, I see it isn't installed but it has enter image description here

I then followed the link in my start menu which went to a webpage to download it. No need to register and it downloaded Utilities and SDK for UNIX-based Applications_X86.exe

 extracted it to C:\sua32

    C:\sua32>dir
     Volume in drive C has no label.
     Volume Serial Number is DC46-3C68

I notice it has a setup.exe (which I will run), and it has files that look like they would be the commands but they have no exe extension.

It includes these files in C:\Windows\SUA\bin>

01/18/2008  06:19 AM               591 whoami

I see no exe extension, and no special shell

How are these meant to run? Or, how am I meant to run these?

I can rename or copy a command e.g. who to who.exe and run it but surely that's not how i'm meant to run it.

How am I meant to run these?

Have you tried simply running C:\Windows\SUA\bin\whoami? A file does not need to be named .exe to be executable. — slhck, Commented Nov 18, 2014 at 12:59
@slhck Just tried it, it didn't run. It said 'c:\windows\sua\bin\whoami' is not recognized as an internal or external command, operable program or batch file. (out of interest, what, if any, setting do you have that can make extensionless files run as executable?) — barlop, Commented Nov 18, 2014 at 13:41
No idea; I'm a Unix person :) But I'd also guess you need to add the bin directory to your PATH. And maybe then these executables just work. — slhck, Commented Nov 18, 2014 at 13:57
@slhck no. you don't need to add the directory to the path if (as you suggested earlier) you give the absolute path(or if you are in the directory and do .\command. i'm largely a windows guy but I know many *nix commands. I already took into account re the path. I just tried adding it to the path, no difference. — barlop, Commented Nov 18, 2014 at 14:04
Do you have Bash or KSH on the start menu somewhere? That works for me. — dsolimano, Commented Nov 18, 2014 at 14:14

While there are only two EXE files in c:\windows\sua\bin (just cat32.exe and fileinfo.exe) and a load of commands that would run but are missing an EXE extension!)

C:\Windows\SUA\bin>dir Volume in drive C has no label. Volume Serial Number is B411-D580

There are EXE files for not all but most of the commands, in c:\windows\sua\common

C:\Windows\SUA\common>

There are some e.g. awk which don't have an exe file but are in c:\windows\sua\bin and you don't have to rename them to run them, they run from an SUA shell e.g. start..programs..subsystem for unix..c shell then ls /bin and awk shows there.

Also, I hadn't noticed initially but installing SUA does add C:\windows\sua\common\ and c:\windows\sua\usr\lib\" (with a trailing backslash oddly enough), to the path.

Related followup question now answered - In Windows SUA(System for Unix Applications), I cannot get KSH to run commands. Even ls fails
