Analysis results will provide useful data for designers of future command interfaces, and they may suggest improvements to the Unix C Shell. The analyses completed to date have shown that a few commands account for the vast majority of the data. In most cases, usage patterns are relatively simple. The average user only uses about one-fifth of all commands, and the vast majority of all command lines contain only one command. Users, however, often alter their environment by using aliases.
