Do You Really Want To Use –EQ?

Steve Lee

Sebastien posted a cool simple script HERE which effectively does a reverse lookup on aliases. Here is the code: function Get-AliasShortcut([string]$CommandName) { ls Alias: | ?{ $_.Definition -eq $CommandName } } Set-Alias gas Get-AliasShortcut Notice that he used –EQ. Whenever you find yourself using –EQ, ask yourself if that is really want you want. You might be cheating yourself out of a ton great stuff. Consider changing the -EQ to -MATCH That would allow you to do: PS> Get-AliasShortcut child

CommandType Name Definition ———– —- ———- Alias gci Get-ChildItem Alias ls Get-ChildItem Alias dir Get-ChildItem

PS> Get-AliasShortcut item

CommandType Name Definition ———– —- ———- Alias cli Clear-Item Alias clp Clear-ItemProperty Alias cpi Copy-Item Alias cpp Copy-ItemProperty Alias gci Get-ChildItem Alias gi Get-Item Alias gp Get-ItemProperty Alias ii Invoke-Item Alias mi Move-Item Alias mp Move-ItemProperty Alias ni New-Item Alias ri Remove-Item Alias rni Rename-Item Alias rnp Rename-ItemProperty Alias rp Remove-ItemProperty Alias si Set-Item Alias sp Set-ItemProperty Alias cp Copy-Item Alias ls Get-ChildItem Alias mv Move-Item Alias rm Remove-Item Alias rmdir Remove-Item Alias copy Copy-Item Alias del Remove-Item Alias dir Get-ChildItem Alias erase Remove-Item Alias move Move-Item Alias rd Remove-Item Alias ren Rename-Item Sebastien – thanks for the cool script!
