Comparative UNIX System Overview
This page contains information about the similarities and differences between different versions of Unix.
This comparative overview is for system administrators who need to apply their expertise on one UNIX platform to a system where they have little or no experience. For example, a veteran Linux administrator who takes a new job that requires Solaris administration skills can determine equivalent (or roughly equivalent) Linux and Solaris commands from this comparative overview.
In each section of the overview, the commands listed produce equivalent or at least similar results. The files that are listed serve the same purpose, but may have different formats. For example, files /etc/fstab and /etc/vfstab perform the same function for different operating systems, but their syntax is quite different. Please be sure to check the appropriate man pages or other references to make sure you know what a command really does and what a file should look like.
For simplicity and to keep the tables a manageable size, only one version of the operating system for a given platform is covered. So, for example, you'll see commands for HP-UX 11.x and Solaris, but none for HP-UX 9.x or SunOS. (If you're interested in more detail, you can check the operating-system versions that were referenced in preparing this overview.)
