Almost without exception Unix is Unix at the user level, especially basic commands and tools, e.g., ls, df, du, awk, grep, etc. Things can vary more at sys admin level though. For example, even among Linux distributions there's the variation in "init", with some distros using SYSV and others using BSD style init schemes. Even at this level though there's usually a root commonality. For example I don't think I've ever run across a Unix system that didn't use /etc/passwd. Even with this variation at the sys admin level, once you've learned one flavor of Unix it's much easier to become familiar with a different flavor. Gary
