Ignore HTTP Return Code for parsing a HTML Site

January 28, 2013, 5:29 am
$

Hello

for our customers we are providing some ACS-Sites. Those sites are just accessable through our security-client. Behind those ACS-Sites our customers run their own webapplications. We don't have access on those application.

We like to monitor those ACS-sites, that we can detect failures/errors before they do. I thought that I could parse the HTML, write it to a textfile and monitore a specific string with our monitoring-tool.

Unfortunately, some applications give back an HTTP 40x error or 50x and the parsing fails. Is there a way, to ignore the returncode and download the website anyway?
We just provide the access to the site and not the application itself. This means if the site shows an application-error, the ACS is accessible

Get-IPAddress PowerShell cmdlet is not Functioning?

Hello everyone!

I am new to Windows PowerShell and I am having difficulty with a particular cmdlet (Get-IPAddress). At the moment my PowerShell prompt does not even recognize the cmdlet. Please see the output below:

PS C:\> get-help get-ipaddress
Get-Help : Cannot find Help for topic "get-ipaddress".
At line:1 char:9
+ get-help <<<<  get-ipaddress
    + CategoryInfo          : ResourceUnavailable: (:) [Get-Help], HelpNotFoundException
    + FullyQualifiedErrorId : HelpNotFound,Microsoft.PowerShell.Commands.GetHelpCommand

Furthermore, I believe I ran this command yesterday (Get-IPAddress google.com) but today if I issue the command I get the following output:

PS C:\> Get-IPAddress google.com
The term 'Get-IPAddress' is not recognized as the name of a cmdlet, function, script file, or operabl
he spelling of the name, or if a path was included, verify that the path is correct and try again.
At line:1 char:14
+ Get-IPAddress <<<<  google.com
    + CategoryInfo          : ObjectNotFound: (Get-IPAddress:String) [], CommandNotFoundException
    + FullyQualifiedErrorId : CommandNotFoundException

May someone please provide insight on this? Does this cmdlet exist? If so, how is my syntax incorrect? I would like to use this cmdlet to resolve hostnames to IP addresses. I know that the commandnslookup also provides hostname to IP address resolution but I would like to learn the Get-IPAddresscommand so that I may create PowerShell scripts.

Thank you in advance for any assistance!

How to keep blank lines from being used as input?

January 25, 2013, 2:10 pm
$

I’m trying to write a simple script to clean up some directories.  However, I don’t want to delete all directories, only the ones in my text file.

Problem- if my text file has a blank line, then I am basically telling my script to delete everything under the parent.  Any way to keep this from happening? (it's easy to have an extra return at the end, or just a blank line somewhere, and I want to safeguard against that).

 

Example- I want to delete users/jdoe but not users/tgun

 

However, if there is a blank line, everything under the users folder gets deleted including tgun. L

 

Current script-

 

 

foreach ($folder in get-content c:\script\deletefolders.txt)

{

               get-childitem c:\users\$folder -recurse |remove-item -recurse -confirm:$false

              "Deleted folder $folder"

 

}

Using PS 3 I'm not able to get to the online version of some of the cmdlets.  For example:

C:> get-help get-content -online
get-help : The online version of this Help topic cannot be displayed because
the Internet address (URI) of the Help topic is not specified in the command
code or in the help file for the command.

Is this a flaw in the current content of the help file update for get-content?

Other cmdlets allow access to the online help.

    $f = [regex]::split($f,'\t|;')
    if($f[0] -eq 'move'){Move-Item $folder1$f[1] $folder2$f[1]}

Select-String in PS v2 - how to prevent expansion of tabs in output

February 2, 2013, 4:41 pm
$
0
0

I am using SELECT-STRING to filter a large tab-delimited text file so I can work with the file in subsets.   However, I find that the resulting output file has had all of the tabs expanded to spaces.  I have been able to reproduce the issue on two different systems running PowerShell v2 under both Windows 7 and Windows 8.  I would like to change this behavior to NOT expand the tabs.  I need to maintain the tab-delimited format because one field in each row can contain a large block of arbitrary text, and 'tab' is one of a very few characters (if not the only) that cannot appear in that field.

How can I prevent tab expansion in SELECT STRING?

Steps to reproduce the issue:

Here is a very simple test case.  Save the following text in a file called test_data.txt:

ID	NAME	STATE
001	Joe	Arizona
002	Bill	Florida
003	Jenny	Colorado
005	Anna	Arizona

Use the following command line to extract a couple of lines:

Select-String -Pattern "Arizona" -Path .\test_data.txt -SimpleMatch | Out-File -FilePath .\test_output.txt

Open test_output.txt in notepad (or another text editor):

test_data.txt:1:001    Joe    Arizona
test_data.txt:4:005    Anna    Arizona

Note that the tabs have been expanded into spaces.

Note also that the following command line returns no results:

Select-String -Pattern "Arizona" -Path .\test_data.txt -SimpleMatch | Select-String -Pattern "`t" -SimpleMatch

This ensures that the behavior is coming from Select-String, not from Out-File.

I have also tested the following command line:

Get-Content .\test_data.txt | ? { $_ -like "*Arizona*" } | Out-File .\test_out.txt
This does not exhibit the same issue, but it appears to run more slowly than using Select-String. 

Thanks in advance for any and all assistance!

How Do I Edit Webpage on a Website That Requires Authentication?

Hello,

I need to edit a webpage on a website that requires me to authenticate on it order to be able to access this web page.

What would you recommend me to implement this simple task:

1. [optional] Fetch data from an URL

2. Post data to the web page by adding text to the end of the form on that web page.

3. Post data to the web page by removing text at the end of the form on that web page.

Say, I want to post a line at the end of the text in web form on a regular basis, and then I want to get this line removed from there.

Would you recommend using Invoke-WebRequest?

Would somebody please assist here?

Thank you in advance.

Well this is the world we live in And these are the hands we're given...
