Using history interactively

The History library provides a history expansion feature similar to the history expansion in csh. 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 (see Event designators). In the second part, select portions of that line for inclusion into the current line. These portions are called words (see Word designators). 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.

The following documentation describes how to use the GNU History Library interactively, from a user’s standpoint.
