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…

  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

August 16th, 2009 2 comments

Not everything you post on the internet needs to be crawled, indexed, and cached by Google or any other search engines. For that very reason a robots.txt file was created, but sometimes we don’t need to get to granular in the robots.txt file, or we may not have access to edit it. For that very reason we can specific information to our META tags in our web pages. 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… Read more…
