Viewing the Command History

You can see all the commands you have already entered by using the history command.

To view the command history:

If you are not already in IDB mode, switch to IDB mode using the following command.

(idb) set variable $cmdset = "idb"

The debugger is now in IDB mode, so you can use the history command.
Enter the following command:

(idb) history

The debugger displays the command history.
If you want to switch to GDB mode, use the following command:

(idb) set $cmdset = "gdb"

GDB Mode:

In GDB mode, the debugger reads the .gdb_history file by default.

To rename the history file:

Set the environment variable GDBHISTFILE to the name of the history file you want to use.

To turn history recording on and off:

Use the set history save command.

To configure the history size:

Use the set history size command or set the environment variable HISTSIZE to the size you want. The default history size is 256.
