ProgrammingThis forum is for all programming questions.
The question does not have to be directly related to Linux and any language is fair game.

Guessing at the algorithm that requires the files to be sorted: file1's server4 and file2's server4 join, but we've already passed server2 in file1, so it's 'wrongly' (for our purposes) skipped when we get to it in file2.
With the files sorted, we exclude both the joined server4 and server2. (That second example uses process substitution and I don't know if that's supported on Solaris, but it's just an example.)
Well, I was thinking it was system-dependent as well as a shell feature. Refreshing my memory with the bash manual, it states, "Process substitution is supported on systems that support named pipes (FIFOs) or the /dev/fd method of naming open files", so it is but of course Solaris supports named pipes and possibly /dev/fd, too, so that was excessive compatibility paranoia.
