![]() $a | ConvertFrom-String | select p2,p3,p4,p5 | where p4 -match '^23' …or a specific part of an IP address, such as this command that finds IP addresses that begin with the number 23: $a | ConvertFrom-String | select p2,p3,p4,p5 | where p4 -match 'mail' The command and its output are shown here: ![]() $a | ConvertFrom-String | select p2,p3,p4,p5 | where p5 -eq 'established' As you can see here, I add where P5 –eq ‘established’: For example, I can filter the output for connections that are established. Now I can easily filter by any property value I want. The output from the command is shown here: $a | ConvertFrom-String | select p2,p3,p4,p5 I simply use Select-Object to select properties P2, P3, P4, and P5: But, when I look at my output, I see that there must be a leading space, so P1 is empty: This is great, because my output from NetStat is delimited by spaces. By default, it will use spaces to create a property on the new object. Now I need to convert the output to objects by using the ConvertFrom-String cmdlet. So, I create a range that skips the first few lines, and continues to the end of my data. Luckily, I know exactly how many lines are in the variable-it is $a.count. What I want is an easy way to skip the first few lines, but keep the remainder of the output. Proto Local Address Foreign Address State When I look at the output from the information stored in my variable, I can see that there are a couple of lines that I do not need: By capturing the output into a variable, I can effectively work offline. I like to store the results from the command into a variable because the output from NetStat is always a bit slow appearing. The first thing I want to do is to capture the output from NetStat. But as of Windows PowerShell 5.0, the script is completely obsolete. I mean it was nearly 20 or so lines long, and it took me a couple of days to accomplish it-but in the end, I was able to output objects that permitted me to filter my output. In the past, I have written complicated scripts to parse the output from NetStat. JK, parsing output from NetStat just got a whole lot easier. Luckily that task just took a giant leap towards simplicity with the new ConvertFrom-String cmdlet in Windows PowerShell 5.0. Augustine where they could go to the beach every day.Īnyway, just like I can count on a summer thunderstorm in central Florida, I can also count on the fact that I am going to have to parse text at some point. I am not sure what people did before air conditioning around here. I mean, summer in central Florida? There are two things one can count on: an afternoon thunder storm and humidity. It hasn’t started raining yet, but I am sure it will. Microsoft Scripting Guy, Ed Wilson, is here. I really need to be able to see stuff like what connections are open, closed, and suspended. I have even gone so far as run the command, copy it to the clipboard, paste it into Notepad, and then go through the Notepad file adding characters so I could import it into Excel and filter the output. ![]() I am not sure if the command itself has a filter language or what, but I really need to be able to parse on the fly. I use it all the time, but it ends up requiring me to spend a lot of time looking through stuff. Hey, Scripting Guy! I need a good way to parse output from the NetStat command. It's fast and I think it's beautiful.Summary : Ed Wilson, Microsoft Scripting Guy, talks about parsing output from NetStat with Windows PowerShell 5.0. I've seen many different versions of a netstat -ano parsing scripts and I know there are powershell alternatives, but I really liked my latest attempt.
