You can learn a given Linux distro, or you can learn Unix. There is a difference. The fast (but painful) way to learn is to work on porting.

- nailer 17y agoAgreed, there certainly is a difference. But 'Unix' is often used as a shorthand for a bunch of committee-created standards that people don't use anymore. Eg, POSIX shell will break when handling file names and data with spaces in them. The defaults in the current Unix OSs - RHEL, SLES, Debian/Ubuntu, OS X, FreeBSD - don't match the 'standard' either - most of these, for example, are moving away from SysV init to something that handles dependencies (rather than starting an SMTP server when there's no network). None of these OSs use SysV packages either. It's certainly valuable to learn multiple Unixs, but make sure that's practical experience rather than an expired 'standard'.
