my gdb config '~/dotfiles/colors.gdb'
```bash
set trace-commands on
shell test -e ~/.gdb-color-pipe && rm ~/.gdb-color-pipe
shell touch ~/.gdb-color-pipe && echo " " >> ~/.gdb-color-pipe && cat
~/.gdb-color-pipe && ls -al ~ | grep gdb
set confirm off
set logging overwrite on
set logging file ~/.gdb-color-pipe
# set logging redirect on

define hook-quit
    shell rm -f ~/.gdb-color-pipe
end

define setup-color-pipe
    set logging enabled on
end

define cleanup-color-pipe
    set logging enabled off 
end

document cleanup-color-pipe
    Disables command redirection and removes the color pipe file.
    Syntax: cleanup-color-pipe
end

sudo add-apt-repository ppa:ubuntu-support-team/gdb
sudo apt update
sudo apt install gdb
# version in ubuntu =12.1.3139.g106791196f98+22.04.20221220200615
