What’s in your PowerShell `profile.ps1` file? [closed]

Question

What essential things (functions, aliases, start up scripts) do you have in your profile?

Answer 1

I often find myself needing needing some basic agregates to count/sum some things., I've defined these functions and use them often, they work really nicely at the end of a pipeline :

# # useful agregate # function count {     BEGIN { $x = 0 }     PROCESS { $x += 1 }     END { $x } }  function product {     BEGIN { $x = 1 }     PROCESS { $x *= $_ }     END { $x } }  function sum {     BEGIN { $x = 0 }     PROCESS { $x += $_ }     END { $x } }  function average {     BEGIN { $max = 0; $curr = 0 }     PROCESS { $max += $_; $curr += 1 }     END { $max / $curr } } 

To be able to get time and path with colors in my prompt :

function Get-Time { return $(get-date | foreach { $_.ToLongTimeString() } ) } function prompt {     # Write the time      write-host "[" -noNewLine     write-host $(Get-Time) -foreground yellow -noNewLine     write-host "] " -noNewLine     # Write the path     write-host $($(Get-Location).Path.replace($home,"~").replace("\","/")) -foreground green -noNewLine     write-host $(if ($nestedpromptlevel -ge 1) { '>>' }) -noNewLine     return "> " } 

The following functions are stolen from a blog and modified to fit my taste, but ls with colors is very nice :

# LS.MSH  # Colorized LS function replacement  # /\/\o\/\/ 2006  # http://mow001.blogspot.com  function LL {     param ($dir = ".", $all = $false)       $origFg = $host.ui.rawui.foregroundColor      if ( $all ) { $toList = ls -force $dir }     else { $toList = ls $dir }      foreach ($Item in $toList)       {          Switch ($Item.Extension)           {              ".Exe" {$host.ui.rawui.foregroundColor = "Yellow"}              ".cmd" {$host.ui.rawui.foregroundColor = "Red"}              ".msh" {$host.ui.rawui.foregroundColor = "Red"}              ".vbs" {$host.ui.rawui.foregroundColor = "Red"}              Default {$host.ui.rawui.foregroundColor = $origFg}          }          if ($item.Mode.StartsWith("d")) {$host.ui.rawui.foregroundColor = "Green"}         $item      }       $host.ui.rawui.foregroundColor = $origFg  }  function lla {     param ( $dir=".")     ll $dir $true }  function la { ls -force } 

And some shortcuts to avoid really repetitive filtering tasks :

# behave like a grep command # but work on objects, used # to be still be allowed to use grep filter match( $reg ) {     if ($_.tostring() -match $reg)         { $_ } }  # behave like a grep -v command # but work on objects filter exclude( $reg ) {     if (-not ($_.tostring() -match $reg))         { $_ } }  # behave like match but use only -like filter like( $glob ) {     if ($_.toString() -like $glob)         { $_ } }  filter unlike( $glob ) {     if (-not ($_.tostring() -like $glob))         { $_ } }
