Some hacks to make linuxing easier

This repo contains a basic set of linux commands injected into a user profile. The hacks/tools are features that I always end up doing manually, all the time, in all the profiles, in all the VMS so I put it all in one place to make things easier.

• aliases - a set of useful aliases for ROS and linux including cleaning out docker.*
• helpers-aws - a set of functions that make working with multiple AWS accounts easier
• helpers-ros - a profile selector and script executor, making working on multiple ROS projects on the same machine easier readme here
• helpers-misc - misc functions like stopwatch, find usage and snaps cleanup
• ps1 - a cool PS1 - overkill for most but handy for me
• git-completion - a direct import of Shawn O. Pearce's gitcompletion implementation
• some commentary on clearing space

This works for linux VM's but is also useful for linux machines and PI's, some of the hacks in here are especially useful running ROS2.

Ubuntu

Removing stuff that I don't need

sudo apt remove --purge -y libreoffice* thunderbird
sudo apt clean && sudo apt autoremove

some more space reduction stuff here

Packages I need

#  update
sudo apt update
sudo apt upgrade -y

# packages i normally use
sudo apt install -y net-tools ssh btop htop vim iftop curl git gcc make \
    build-essential libssl-dev zlib1g-dev libbz2-dev screen tmux \
    libreadline-dev libsqlite3-dev wget curl llvm libncurses5-dev libncursesw5-dev \
    xz-utils tk-dev libffi-dev liblzma-dev

Profile helpers, including the ros bit

ln -sf ~/linux_profile/.vimrc ~/.vimrc
ln -sf ~/linux_profile/.editorconfig ~/.editorconfig
ln -sf ~/linux_profile/.tmux.conf ~/.tmux.conf

echo 'source ~/linux_profile/profile.sh humble' >> ~/.bashrc
# the 'humble' bit is to source in the ROS bash file
# it works for whatever the ROS folder is called - this could be done more elegantly
source ~/.bashrc

Git

git config --global user.email "[email protected]"
git config --global user.name "your name"
git config --global push.autoSetupRemote true
git config --global pull.rebase true

ssh autostart

sudo systemctl enable ssh
sudo systemctl start ssh

Add sudoers to Sudoers as nopasswd

%sudo   ALL=NOPASSWD: ALL

pyenv

pyenv from here

check the script is sane and then:

curl https://pyenv.run | bash

Then install something python'y

pyenv install 3.13
pyenv global 3.13

#this assumes you're importing the profile.sh in your .bashrc
