If you are like me, you’re starting to develop a lot of aliases and custom functions. The thing is, I can’t always remember what every function or alias does. Fortunately, that is pretty easy to discover.For example, I have an alias called du<\/p>\n
CommandType Name Definition<\/span> <\/font>But what did I create for Get-DiskUsage? Piping the Get-Alias command through Get-Member gives me this: Ahhhh. I think Resolvedcommand might get me what I need. So I try this:<\/p>\n PS S:\\ > (get-alias du).ResolvedCommand Yes. I can see the definition but it is trunctated. Easily fixed with a little formatting. (code formatting in the blog leaves a little to be desired but you get the idea.)<\/p>\n PS S:\\ > (get-alias du).ResolvedCommand |format-list<\/span> # in case the user wants to see more than just local drives$filter = “DriveType = ‘3’”if ( $all ) { $filter = “” }<\/p>\n # go do the work by getting the information from the appropriate If I only want to see the definition I can use an expression like this: Now I can see the full function definition. Now that I know the shortcut, I can try it out on another alias:<\/p>\n PS S:\\ > (get-alias fs).resolvedcommand.definitionparam([string]$Computer) $results=Get-WmiObject -class win32_logicaldisk -computername $Computer| `where {$_.drivetype -eq 3} | select DeviceID,VolumeName,Size,FreeSpace<\/p>\n foreach ($drive in $results) {$obj = New-Object System.Object$sz=”{0:N2}” -f (($drive.Size)\/1MB)$fs=”{0:N2}” -f (($drive.Freespace)\/1MB)<\/p>\n Add-Member -inputobject $obj -membertype NoteProperty -Name DeviceID -value$drive.DeviceID PowerShell<\/a> Scripting<\/a><\/p>\n","protected":false},"excerpt":{"rendered":" If you are like me, you’re starting to develop a lot of aliases and custom functions.
