The name of the "/usr" directory is the latter. At one point in time in the ancient past, the /usr directory is where user directories were once stored, but over time the usage of this directory changed. The claim of 'usr' being an abbreviation for Unix System Resources is a "backronym," (i.e. an abbreviation created after the fact). jcr -- The OpenBSD Journal - http://www.undeadly.org
