UNIX Explanation
The history command performs one of several operations related to recently-executed commands recorded in a history list. Each of these recorded commands is referred to as an ``event''. When specifying an event to the history command, the following forms may be used: [1] A number: if positive, it refers to the event with that number (all events are numbered starting at 1). If the number is negative, it selects an event relative to the current event (-1 refers to the previous event, -2 to the one before that, and so on). Event 0 refers to the current event. [2] A string: selects the most recent event that matches the string. An event is considered to match the string either if the string is the same as the first characters of the event, or if the string matches the event in the sense of the string match command.
