Shrinking your Url’s is all the rage nowadays.  If you are on Twitter, then odds are you have used one.  Despite CodingHorror’s distaste for them in his recent blog post on Url Shorteners: Destroying the Web since 2002, they are a fact of life when we live in a world of 140 character status updates. So what’s a URL shrinking service anyway?  Well, to put it simply, you supply them with a URL, they then supply you with a shorter URL containing a lookup “key”.  When future requests are made to this shorter URL, connections are routed to that services website where they convert the short URL to the original URL and issue a HTTP Redirect back to your browser to send you off to the original long url website. So, what’s a guy, or gal, to do if they want to set their status programmatically on Twitter, Facebook, FriendFeed, or the other gazillion social networking sites ... (more)

Unix To PowerShell - Wc

PowerShell is definitely gaining momentum in the windows scripting world but I still hear folks wanting to rely on unix based tools to get their job done.  In this series of posts I’m going to look at converting some of the more popular Unix based tools to PowerShell. wc The Unix “wc” (word count) command will print the character, word, and newline counts for each file specified and a total line if more than one file is specified.  This command is useful for quickly scanning a directory for small and large files or to quickly look at a file and determine it’s relative size.  The...

Unix To PowerShell - Seq

PowerShell is definitely gaining momentum in the windows scripting world but I still hear folks wanting to rely on Unix based tools to get their job done.  In this series of posts I’m going to look at converting some of the more popular Unix based tools to PowerShell. seq The Unix “seq” command prints a sequence of numbers from FIRST to LAST, in steps of INCREMENT. The PowerShell “range” operator “..” will return an array of numbers but it does not give you the ability to modify the increment from 1 (or –1 if the LAST is smaller than FIRST).  I accomplished this with a simple for...

Unix To PowerShell – Cut

PowerShell is definitely gaining momentum in the windows scripting world but I still hear folks wanting to rely on Unix based tools to get their job done.  In this series of posts I’m going to look at converting some of the more popular Unix based tools to PowerShell. cut The Unix “cut” command is used to extract sections from each link of input.  Extraction of line segments can be done by bytes, characters, or fields separated by a delimiter.  A range must be provided in each case which consists of one of N, N-M, N- (N to the end of the line), or –M (beginning of the line to M)...
