Combine or Join Two Text Files Using PowerShell

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. […]

Add or Map a Custom Hostnames to IP Address without a DNS Server

There’s been several times where I had an Apache server running locally on my computer as a development (or dev) server. Now if this is on my home network, or if your system administrator won’t give you your own custom host name then you have to go the DIY (do it yourself) route.

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. […]

Check If File Exists with VB.NET

I was creating an application in Visual Basic the other day and I couldn’t remember how to check to see if a file exists, so I thought I would do a quick example to see if a file exitsts.

Pass Credentials via PowerShell

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

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

Preventing Google and Other Search Engines From Indexing Your Website Using Meta Tags

Not everything you post on the internet needs to be crawled, indexed, and cached by Google or any other search engines.

The robots field is a comma separated list, if you do not set it, it will automatically default to ALL, this means that the page can be indexed and that all links on the page can be crawled. Here is the api for the robots field… […]
