The above version easier to read and "copy paste". Space is space and tabe is \t
sed 's/^([^ \t]*[ \t]*[^ \t]*)([ \t]*.*)$/\1.contoso.com\2/'
I grew up with versions of 'sed' that don't understand this new-fangled method of specifying tabs, and write enough cross-platform code that I can't rely on it (still doesn't work in Solaris 10, for example).
perl can do anything sed can do and has almost no platform or version related syntax differences - plus it has \s to represent 'whitespace' and you don't have to bang your head on the wall when you are half done and realize you have to do something spanning multiple lines.
Show your example. Inquiring minds want to know!
