PowerShell Script to get list of links on a webpage

Note that you can run a PowerShell script to get a list of all of the hyperlinks on a web page. On any PC running Windows 10, open PowerShell ISE, and simply put this script:

(Invoke-WebRequest -Uri “https://www.supremecourt.gov/opinions/slipopinion/20”).Links | sort-object href -Unique | Format-List innerText, href

. . . in the Script Pane, the white area on the top. (Display this area under the View menu, if you don't see it after opening PowerShell.) The actual web address, as you can see, is entered after '-Uri' in double quotes.

So from this web page:

. . . we get these results after pressing the play button on the toolbar in PowerShell.

Checking FASP Connection for RelativityOne

In order for RelativityOne to transfer data from a user's computer to Relativity server, it must be able to use multiple UDP ports to transfer data via the Fast Adaptive and Secure Protocol (FASP), which uses Port 33001. In order to see if a network is configured to transmit data to a fully qualified domain name via the FASP port run this PowerShell script:

Test-NetConnection -ComputerName [FQDN] -Port 33001

. . . FQDN being the fully qualified domain name. If a domain can be reached the value listed for the 'PingSucceeded' value will be true. If the specified port can be accessed then TcpTestSucceeded will also be true.

PowerShell Script to compare the hash values of multiple files

You can use the below PowerShell script to compare the hash values of multiple pairs of files.

Begin by giving each path for each file in your data set a unique name.

$file1 = "C:\foofolder\set1\analysis.xlsx”

$file2 = "C:\foofolder\set2\analysis.xlsx"

$file3 = "C:\foofolder\set1\Memo.docx”

$file4 = "C:\foofolder\set2\Memo.docx"

$file5 = "C:\foofolder\set1\Show1.pptx”

$file6 = "C:\foofolder\set2\Show1v2.pptx"

. . . then prepare lines comparing the hash of the first file to the second file:

if((Get-FileHash $file1).hash -ne (Get-FileHash $file2).hash)

. . . . you can parse through your data on an Excel spreadsheet like this:

. . . using a formula to number the files side by side. Copy the lines to a text editor and remove the resulting tabs, putting each line of script on a new line as necessary.

The script will give you a list of which files are same and which are different in the same order in which they are listed in the script.

$file1 = "C:\foofolder\set1\analysis.xlsx”

$file2 = "C:\foofolder\set2\analysis.xlsx"

$file3 = "C:\foofolder\set1\Memo.docx”

$file4 = "C:\foofolder\set2\Memo.docx"

$file5 = "C:\foofolder\set1\Show1.pptx”

$file6 = "C:\foofolder\set2\Show1v2.pptx"

if((Get-FileHash $file1).hash -ne (Get-FileHash $file2).hash)

{“files are different”}

Else {“Files are the same”}

if((Get-FileHash $file3).hash -ne (Get-FileHash $file4).hash)

{“files are different”}

Else {“Files are the same”}

if((Get-FileHash $file5).hash -ne (Get-FileHash $file6).hash)

{“files are different”}

Else {“Files are the same”}
