You could customize the info about the process, and even combine these into a single pipeline which gets the socket info PLUS the process info, but I'd need more exact requirements. OTOH if you actually wanted remote port 443 (which doesn't really make sense with -a) do -remoteport 443.īy default the nettcpconnection structure doesn't display the owning process but that can be overridden with format-table, which automatically supplies the header lines, and additional information about a process can be obtained by a different cmdlet get-processĪs a worked example I don't have anything on 443, but do have a virtualbox listening on 7022: PS C:\work> get-nettcpconnection -localport 7022 |format-table localaddress,localport,owningprocess Adding -localport 443 does this filtering - and does NOT include sockets which use port 4437 or 14430 or 22443 or have pid 4430 or remote port 443 or 4439, which you text search will include but you don't actually want. I assume you used -a because you want to include sockets in listen state and really want to find the process(es?) using local port 443 not remote. Instead of searching text output for a substring, you can filter values. Instead of running a program (netstat) to get info about TCP connections (or more exactly socket endpoints) you can use the 'cmdlet' get-nettcpconnection I like to store the results from the command into a variable because the output from NetStat is always a bit slow appearing. It's not an answer to the question you asked, but in general on (non-ancient) Windows a lot of things you do on Unix in text form can instead by done in PowerShell with properly typed data, more like SQL or JSON than shell. The first thing I want to do is to capture the output from NetStat. Grep’s core is simply the ability to search plain text for a RegEx pattern. Select-Object -Skip 3).trim()) -replace '\s\s+', ',') | This venerable tool has been around for decades and is crucial to any administrator’s toolbelt. For example: netstat -aonp TCP | findstr /i /c:"proto" /c:"135" /c:"443" powershell script to collect Name, IP and mac addresses from my active directory. In DOS/CMD.exe, it's a bit more cumbersome, and you'd lean toward 'FINDSTR' instead of just 'FIND'. The Get-Help cmdlet displays help at the command line from content inīut if PowerShell is available then you can use its Select-String cmdlet directly.You can also use RegEx match to 'OR' things up. Or if you don't need Unicode support then you can simply find with findstr which doesn't need the quotes PS C:\Users> help | findstr command instead of running a program (netstat) to get info about TCP connections (or more exactly socket endpoints) you can use the 'cmdlet' get-nettcpconnection instead of searching text output for a substring, you can filter values. This can be used to call a non-PowerShell utility and pass along some quoted parameters exactly as is.Īs a result you can use it like this find.exe -% "" *.ps1xml In PowerShell 3.0 the special marker -% is a signal to PowerShell to stop interpreting any remaining characters on the line. However there's an easier way with Verbatim arguments -% In simple cases like this when there's no space in the parameter you can also escape the double quotes directly without putting it inside another pair of quotes find.exe /i `"`" *.ps1xml This can be used to call a non-PowerShell utility and pass along some quoted parameters exactly as is. You also have a standardized way to pass special characters in parameters similar to bash, unlike in cmd where embedded double quotes are a painĪccording to PowerShell quoting rule you must escape the quote by either `backticks` or the double quote itself, or simply put it in single quotes like above In PowerShell 3.0 the special marker - is a signal to PowerShell to stop interpreting any remaining characters on the line. IMHO it's a good thing because now you can use single quotes to wrap strings. You can check it by echoing or writing the string directly in command line PS C:\> echo C:\Windows\System32\find.exe /i "" *.ps1xml See PowerShell stripping double quotes from command line arguments. Or use verbatim arguments find.exe -% "" *.ps1xmlĪs Peter Hahndorf said, PowerShell is stripping the outer quotes. Escape the double quotes or put the string inside single quotes find.exe /i "`"`"" *.ps1xmlįind.exe /i """""" *.ps1xmlįind.exe /i '""' *.ps1xmlįind.exe /i `"`" *.ps1xml
