Question

I want to fetch Windows Hotfix listing with some format, whose output can be separated with some delimiter. so far I found a wmic command which gives me a desired output but the problem is the \s delimiter is not going to work here. Is there a way I can place some , or anyother character, which I can later use in java program to get individual columns?

Command

wmic qfe get caption,csname,description,hotfixid,installedby,installedon

Output

Caption                                        CSName    Description      HotFixID   InstalledBy          InstalledOn

Update

I am trying

for /f "tokens=1,2,3,4,5,6,7,8,9,10,11" %g in ('wmic qfe get caption,csname,description,fixcomments,hotfixid,installdate,installedby,installedon,name,servicepackineffect,status') do @echo %g,%h,%i,%j,%k,%l,%m,%n,%o,%p

but it gives me invalid GET Expression

C:\Users\Abhishek\Desktop>for /f "tokens=1,2,3,4,5,6,7,8,9,10,11" %g in ('wmic qfe get caption,csname,description,fixcomments,hotfixid,installdate,installedby,installedon,name,servicepackineffect,status') do @echo %g,%h,%i,%j,%k,%l,%m,%n,%o,%p
Invalid GET Expression.

What is the problem here? This might solve the problem for me .

More Update

I even tried the below command but this too does not solve space problem

Command

for /f "tokens=1,2,3,4,5,6,7,8,9,10,11" %g in ('wmic qfe list') do @echo %g,%h,%i,%j,%k,%l,%m,%n,%o,%p

Output

Answer 1

As I can see in the result of wmic, columns are separated at least by 2 spaces.

Caption                                        CSName    Description      HotFixID   InstalledBy          InstalledOn

http://support.microsoft.com/?kbid=2032276     Abhishek  Security Update  KB2032276  NT AUTHORITY\SYSTEM  3/15/2012

So this can be easily parsed in Java by splitting with the \s{2,} regular expression :

String result = "...";
for (String line : result.split("\n")) {
     System.out.println("-> " + line);
     for (String column : line.split("\\s{2,}")) {
         System.out.println("  => [" + column.trim() + "]");
     }
 }

Outputs:

-> Caption                                        CSName    Description      HotFixID   InstalledBy          InstalledOn
  => [Caption]
  => [CSName]
  => [Description]
  => [HotFixID]
  => [InstalledBy]
  => [InstalledOn]

For the batch side, I cannot help you as I know really nothing about it 🙂

Edit:
Apparently there is a switch /format:csv for wmic that should generate a CSV that you could also easily parse in Java. I cannot get it to work on my machine, but it’s worth to be noticed.
