GDB can keep track of the commands you type during your debugging sessions, so that you can be certain of precisely what happened. Use these commands to manage the GDB command history facility.
set history filename fname
GDBHISTFILE, or to `./.gdb_history' if this variable is not set.
set history save
set history save on
set history filenamecommand. By default, this option is disabled.
set history save off
set history size size
HISTSIZE, or to 256 if this variable is not set.
History expansion assigns special meaning to the character !.
Since ! is also the logical not operator in C, history expansion
is off by default. If you decide to enable history expansion with the
set history expansion on command, you may sometimes need to
follow ! (when it is used as logical not, in an expression) with
a space or a tab to prevent it from being expanded. The readline
history facilities do not attempt substitution on the strings
!= and !(, even when history expansion is enabled.
The commands to control history expansion are:
set history expansion on
set history expansion
set history expansion off
vimay wish to read it.
show history filename
show history save
show history size
show history expansion
show historyby itself displays all four states.
