I noticed that my command history remains only during the current session, and once I re-start ddd, say with the same process, it starts with a clean slate. Is there way I can force the latest history to persist/reload.

I couldn’t find any relevant options in Edit-> Preference/GDB sessions.

I am using GNU DDD 3.3.9 (i386-redhat-linux-gnu)

    I am not using DDD. Am using GDB command line on an ubuntu box. This answer may be useful to those who want to save their gdb history within sessions:

    As per the documentation available: here, history saving is disabled by default. To enable it and to do so everytime I run gdb, I did the following:

    1. Edited ~/.bashrc file to have the line “export GDBHISTFILE=”$HOME/.gdb_history”. This will save the history in this file. You may want to keep a size check on it which is described in the link.
    2. Edited ~/.gdbinit to have the lines:
      set history save on
      set history expansion on
    3. ran gdb

    When I quit and restarted gdb, I was able to access previous sessions commands. I use the vi mode in gdb (Esc + Enter) and doing a “Ctrl + r” shows me previous listings. Hope this helps.
