whoami: a pedestrian user id retriever

whoami displays a full user id and retrieves system properties

Description

WHOAMI displays a long user id (LID) in the form
%time|username|domain|hostname|osarch|osname|osver|MLver
 
WHOAMI optionally returns various system properties including a short user id (SID), which only contains static information about the current system
programmers can easily create their own IDs or change the built-in formats, which may be a useful tag in source control

example of the short output (note: formatting will most likely be bad)

>> w=whoami;
>> w
        magic: 'WHOAMI'
    WHOAMIver: '18-Jun-2008 13:47:52'
        MLver: '7.6.0.324.R2008a'
      runtime: '18-Jun-2008 14:02:09'
          sid: '%us|USZ|ws-nos-36362|x86|Windows XP|7.6.0.324.R2008a'
          lid: [1x77 char]

• Acknowledgements: This submission has inspired the following:; getUserName
• MATLAB release: MATLAB 7 (R14)
• Other requirements: the java engine must be loaded; the code was tested on various wintel systems only but SHOULD run on other systems as well

Really poor!! and requires "wintel systems". User can get all this info with two lines of code of some extension, and without requirements!

dear D Slav
thank you for your catchy comments...
firstly, i did not say requires wintel systems, i simply said: tested on wintel systems - after all it's using java...

then, i'd be very interested to see those two lines you mention... very interested...

did you even look at/run the snippet...

(Tested the original version.) Does not require a wintel system. I just tested it on my mac - runs fine.

[Kevin J. Delaney]

Works great on my Windows system! Nicely done.

if (isunix)
    user = getenv('USER');
else
    user = getenv('username');
end
