If you just want to list all the sites (ie. to find a binding)
Change the working directory to "C:\Windows\system32\inetsrv"
cd c:\Windows\system32\inetsrv
Next run "appcmd list sites" (plural) and output to a file. e.g c:\IISSiteBindings.txt
appcmd list sites > c:\IISSiteBindings.txt
Now open with notepad from your command prompt.
notepad c:\IISSiteBindings.txt
