Download File with a PowerShell One-Liner

December 11th, 2011 No comments

I was recently trying to automate some scripts on a linux box and I wanted to know if it was as simple to download a file in PowerShell as it is in linux: wget http://example.com/file.jpg

Well as it turned out, it wasn’t, but it wasn’t that difficult either. What we needed was too use the System.Net.WebClient class. There’s one thing to note, in PowerShell you can’t use a ~ (tilde) to reference your home directly, that is to say, you can’t download a file to ~\Desktop you will need to specify the full path, in my case C:\Users\Brangle\Desktop.

Make PowerShell Talk / Speak

December 9th, 2011 No comments

Have you ever run a long PowerShell script, minimized it, only to realize much later that an error caused it to stop? Rather than just using a color syntax red to display the error,  I wanted to hear it so I could switch back to the PowerShell window and see the error.

So how easy is it to make PowerShell speak? It’s almost identical to the .NET code I have in VB.net and C# on Make Your Computer Talk with VB.NET Application (and Source Code) using the SAPI.SpVoice class. Read more…

Combine or Join Two Text Files Using PowerShell

August 26th, 2009 2 comments

Merging files together, or to a seperate file, is a snap with PowerShell using the Get-Content cmdlet. If you’ve never used the Add-Content cmdlet, I would suggest first reading my other article Append Text to a File Using Add-Content. The first thing we need to do is identify our two files, in my case I’ll be using file1.log and file2.log. In the first example, I append all the text of file2.log into the end of file1.log. In the second example, I’ll create a completely new file and dump the contents of both the files into the newly created file. In the last example, I’ll add the current date to the filename of a completly new log file. Read more…

Pinging a computer is really simple, and of course since this is PowerShell we don’t want to use something as primitive as ping.exe, we want to use .NET and take advantage of all the method calls and filters. Read more…

Send eMail and SMS Text Messages with PowerShell

August 23rd, 2009 No comments

Thanks to the .NET library sending emails with PowerShell is surprisingly very simple! One thing to remember is line breaks, when you need a new line, make sure to use the escape characters `n . In the first example, I’ll send just a regular email, in the second I’ll send a SMS text message. Read more…

Pass Credentials via PowerShell

August 23rd, 2009 No comments

I’ve often found it necessary to pass my Administrator domain or Domain Admin (DomAdmin) credentials to run a PowerShell WMI command. Fortunately PowerShell provides 3 different ways of doing just that, not counting using Windows built in runas command. The three methods I’m going to go over are

  1. Entering your own unique credentials
  2. Entering a service account password, ie: the same username (or hard coding a username)
  3. Hard coding a user name and password

Mounting a Virtual/Network Drive with PowerShell

August 13th, 2009 1 comment

There’s multiple reasons why someone would want to mount a virtual or network drive, especially in an enterprise environment where many users don’t understand the concept of UNC paths or when older software doesn’t support long path names or UNC connections. Now there’s two things we need to know, is this a local path, or is it somewhere on the network. Once we know that we can get started. Read more…
