Get-FavoritesFQDN.ps1

# This can help you detect which shortcuts from IE are internal or external
# you may want to migrate/backup/sync https://gist.github.com/pohatu but not
# something like http://secret/internal/site

# madprops to madprops for below snippet
#http://madprops.org/blog/list-your-favorites-in-powershell/

$favs = gci $env:userprofile\favorites -rec -inc *.url |
    ? {select-string -inp $_ -quiet "^URL=http"} | 
    select @{Name="Name"; Expression={[IO.Path]::GetFileNameWithoutExtension($_.FullName)}},
        @{Name="URL"; Expression={get-content $_ | ? {$_ -match "^URL=http"} | % {$_.Substring(4)}}}
        
# With this, then pipe the .url from each of these shortcuts to resolve-dnsname, and get the Name
# Name is FQDN, basically
# Resolve-DNSName chokes on urls like http://foo/ or http://foo/myawesomepage.html
# so [URI]($_.url).Host gets the foo out of http://foo/myawesomepage.html
# and resolve-dnsname ().Name will return something like foo.mydomain.mycorp.com
# so input will be http://foo/myawesomepage.html and output will be foo.mydomain.mycorp.com

$myFavs = ($favs | % { @{Name=$_.name; FQDN=(Resolve-DnsName ([URI]($_.url)).Host).Name}})
