Solved PowerShell programing: simple issue

rahul1911 · Dec 14, 2010

My apologies if this is not the correct place to put up this question, but i saw that the PowerShell section is archived now, so had to put in here.

I am very new to the Powershell programing and trying out a very simple thing but failing.
Situation : for some code I am trying to compare two different integer values and getting the wrong result, below is the simulated code for :
************************************
[int] $a=5
[int] $b=3
if($a > $b)
{write-host "working"}
else
{write-host "not working"}
************************************
Now my problem is that when i press enter it prints "not working", which would mean that value b> value a, which is incorrect. Am I going wrong somewhere?
Please help.

Thanks

this is the exact copy paste of the output from the PowerShell console Window :

PS C:\Documents and Settings\abc> [int] $a =5
___________________________________________________________________________________________________________________________
PS C:\Documents and Settings\abc> [int] $b =3
___________________________________________________________________________________________________________________________
PS C:\Documents and Settings\abc> if($a > $b)
{write-host "working"}
else
{write-host "not working"}
not working

Hello, and welcome to the Vista Forums!

This may seem a little odd to begin with. ">" is not actually valid in Power Shell. You have to do something very strange!

Here is your code, corrected:

Code:

[int] $a=5
[int] $b=3
if($a -gt $b)
{write-host "working"}
else
{write-host "not working"}

Output:

Code:

________________________________________________________________________________________________________________________________________________________________________
PS C:\Users\Richard\Documents> C:\Users\Richard\Documents\test.ps1
working

________________________________________________________________________________________________________________________________________________________________________

You are probably now thinking "what on earth"!

-gt: Greater than.
-cgt: Case sensitive greater than

Have a look at this webpage: A Quick guideline for Microsoft Windows PowerShell Part-1. - CodeProject

In particular, look at the table of comparators near the bottom.

Persevere, and you will be rewarded! Have fun, and good luck!
