One of the things I want us to consider doing in the future is to leverage our Universal Code Execution infrastructure to execute any kind of code. For example, imagine that I have some script foo.vbs, I\u2019d like to do the following:<\/p>\n
PS> Invoke-Command \u2013FilePath foo.vbs \u2013computer (cat servers.txt)<\/p>\n
I was about to file a record for us to consider this and thought \u2013 wait \u2013 I bet that there are other commands that take a FilePath need to be updated as well. The question is \u2013 which commands take the FilePath parameter? As I write this up, I now remember the correct solution to this question. We all know that you can Get-Help on a command like Invoke-Command <\/p>\n
PS> Get-Help Invoke-Command<\/font> But did you realize that you can also get help about the parameters of a command? <\/p>\n PS> Get-Help Invoke-Command -Parameter FilePath <\/font><\/p>\n -FilePath <string> <\/p>\n <\/p>\n A lot of people know that one but I wonder how many people realized that you can actually omit the command name to find all the commands that use a parameter:<\/p>\n PS> get-help * -Parameter FilePath <\/font><\/p>\n Name Category Synopsis <\/p>\n Pretty awesome isn\u2019t it?<\/p>\n <\/p>\n But here is the deal \u2013 I forgot about that when I had the problem so I wrote myself a quick and dirty script that gave me exactly what I needed. Notice that when I\u2019m writing throw away scripts, I almost allows name them \u201ct\u201d or \u201ct1\u201d or \u201ct2\u201d\u2026 Why? Because its easy to type and I\u2019m throwing the thing away when I\u2019m done.<\/p>\n PS> function t ($p) {gcm -Type Cmdlet |where {$_.Parameters.$p}} CommandType Name Definition <\/p>\n <\/p>\n <\/p>\n That was the real point of this blog \u2013 that sometimes you just want to write a quick and dirty script and that is perfectly OK \u2013 you can skip all the best practices and just go go go! <\/p>\n <\/p>\n But wait \u2013 it get\u2019s better. When I looked at the output of those 2 approaches, something didn\u2019t seem right so I thought I would do a little more investigation<\/p>\n PS> $x1 = get-help * -param filepath |select -expand name |sort InputObject SideIndicator PS> get-help New-WSManInstance -param f* |select name <\/font><\/p>\n name <\/p>\n So what that means is that we have a documentation bug (a benign one but still a bug). It has documented the parameter as \u201cFILE\u201d when in fact it is \u201cFILEPATH\u201d.<\/p>\n <\/p>\n <\/p>\n I gotta tell you \u2013 I just LOVE working with PowerShell. It makes you feel so POWERFUL. That sounds corny and trite but it\u2019s true!<\/p>\n Go have some fun!<\/p>\n Jeffrey Snover [MSFT] One of the things I want us to consider doing in the future is to leverage our Universal Code Execution infrastructure to execute any kind of code.

Runs the specified local script on one or more remote computers. Enter the path and file name of the script, o
r pipe a script path to Invoke-Command. The script must reside on the local computer or in a directory that th
e local computer can access. Use the ArgumentList parameter to specify the values of parameters in the script.
When you use this parameter, Windows PowerShell converts the contents of the specified script file to a script
block, transmits the script block to the remote computer, and runs it on the remote computer.
Required? true
Position? 2
Default value
Accept pipeline input? false
