Unix is a multitasking, multi-user computer operating system originally developed in 1969 by a group of AT&T employees at Bell Labs.

Excerpt from the Wikipedia page

Unix was originally written in assembly but has since been rewritten in C. It has been branched many times both commercially and open source. One popular variant is the BSD variant which originated from the University of California, Berkeley. It also gave rise to Linux.

Notable variants

  • Silicon Graphics - Irix
  • IBM - AIX
  • Sun Microsystems - Solaris
  • Hewlett Packard - HP-UX

Unix is officially trademarked as UNIX.

Tar: create new archive from filtered archive

I need to create a new tar archive from the filtered output of the original. I thought something like this might work: tar xvpf myarchive.tar --exclude=foo* | tar cvpf mynewarchive.tar but that doesn't. Any ideas? Thanks!
