History interaction

The History library provides a history expansion feature similar to the history expansion in csh. The following text describes the syntax you use to manipulate history information.

History expansion takes two parts. In the first part, determine which line from the previous history will be used for substitution. This line is called the event. In the second part, select portions of that line for inclusion into the current line. These portions are called words. GDB breaks the line into words in the same way that the Bash shell does, so that several English (or Unix) words surrounded by quotes are considered one word.
