The goal here is to remove duplicate entries from the PATH variable. But before I begin, let's be clear: there's no compelling reason to to do this. The shell will, in essence, ignore duplicates PATH entries; only the first occurrence of any one path is important. Two motivations drive this exercise. The first is to look at an awk one-liner that initially doesn't really appear to do much at all. The second is to feed the needs of those who are annoyed by such things as having duplicate PATH entries.

How music listeners can fill the industry's "value gap". From the 1940s to the 1960s, countless millions of people would put a dime in a jukebox to have a single piece of music played for them, one time. If they wanted to hear it again, or to play another song, they'd put in another dime.

Dmitry Safonov wanted to implement a namespace for time information. The twisted and bizarre thing about virtual machines is that they get more virtual all the time.

It was white, not much bigger than my hands held side by side, weighed about as much as a bottle of wine, and it came in a shiny, faux-leather case. It was the $199 Asus Eee 901, and I couldn't believe that a computer could be that powerful, that light and that much fun.
