Solaris has always (?) had sdiff

It is not really necessary to add diffutils to Solaris for side-by-side diff comparisons. It may be useful for consistency in scripts, but side-by-side diff is more of a human interface and not really a scripting tool.

I have been using Solaris (on SPARC) for about 13 years (and SunOS before that). It has always had sdiff. I can't remember if it was in SunOS since that was a while ago.

As I recall, sdiff was used under the graphical interface for WorkShop (the compiler tools).

tkdiff

As always I enjoyed your article Sandra. Just wanted to add I've come to really like using tkdiff, a very nice graphical wrapper around diff that is very portable. I found it here http://sourceforge.net/projects/tkdiff .

vimdiff

For those with color terminals and vim installed, "vimdiff" is quite intuitive, especially if you're used to running split screen vim.

Sidekick: The Good News & the Bad News
Either way you look at it Microsoft Data Center management did not follow standards or best practices in this failure. In which case it makes me wonder more about the outsourcing of corporate data much less personal data.
