Scripts

I write these scripts for my own use, and you may need to tweak them slightly to suit your needs.

Never run a script you can't read or understand. Comments can be found in the scripts, usually explaining them block-by-block. Below is my personal use cases for the scripts, to provide further insight into how I use them and how they might be useful to you.

adduser.sh

This script was made on Ubuntu when creating a few users across multiple hosts. Syntax requires at least 2 arguments when running the script, otherwise help text will be output warning of correct usage and available options. The script can be used to configure sudo on a new user if the script itself is ran with sudo. Otherwise, creating a default user with or without a password is possible without sudo. If the script is ran on an existing user or a userID that is already in use is passed, no changes will happen in user-creation but you may still allow the user to sudo and change their password.

Syntax -

./adduser (Help text) ./adduser jeff 1005 (Create user jeff with userID 1005, can't configure sudo, prompt for possible password creation)

sudo ./adduser (Help text) sudo ./adduser jeffy 1010 (Create user jeffy with userID 1010, can configure sudo, possible password creation)

Didn't configure sudo, and don't want to do so manually? Re-run the script on the existing user just as above, and accept the prompt for sudo configuration. sudo ./adduser jeff 1005 (User creation will fail, follow prompts to configure sudo and / or reset user password)

cmake-build.sh

I usually run this script within whatever directory I'm working in, hence the infinite loop, I leave the script running until I'm done with my work and move to a new directory / cmake project.

setup-vim.sh

To use this script, run sudo ./setup-vim.sh as seen below. Vim configs used for this script are stored in /etc/config-vim/. When the script runs into previous vimrc configs they are backed up into /etc/config-vim/backups/

cloud_user@shaunrd03c:~$ ./setup-vim.sh 
This script must be ran with sudo...
sudo ./setup-vim.sh
cloud_user@shaunrd03c:~$ sudo ./setup-vim.sh 

Enter 1 to configure vim with the Klips repository, any other value to exit.

Vim has been configured with the Klips repository.

Configuration Changes: 
~
Packages Installed / Updated:
- vim, git, clang

Vimrc Settings:
- tabwidth is 2, and set to insert SPACE characters instead of TAB symbols with expandtab
- shiftwidth is 2 so we can compensate for the conflict with default tab settings
- autoindent is on, when moving to a newline vim will indent to the current depth
- syntax highlighting is on
- mouse interaction is enabled when supported by connecting systems
-- https://github.com/shaunrd0/klips/tree/master/configs

Plugin Settings:
- Pathogen vim plugin manager has been installed and .vimrc configured for its use.
-- Install new vim plugins by cloning their repositories into ~/.vim/bundle/
-- https://github.com/tpope/vim-pathogen

- Clang_complete vim plugin has been installed and .vimrc configured for its use.
- Code-completion is enabled with default clang_complete settings
-- https://github.com/xavierd/clang_complete
--If you have issues with Clang_complete library linking / loading, check the directory / commands below - 
cd /usr/lib/x86_64-unknown-linux
ln -s libclang.so.1 libclang.so

- Supertab vim plugin has been installed and .vimrc configured for its use.
- Allows the use of TAB to enable code-completion context menu
-- https://github.com/ervandew/supertab

- Enable nocp
-- Ensures vim is not set to be compatible with older versions of vi
-- Removing this could diable enhancements on some systems
-- :help 'compatible' within vim for more information

- Define backspace scope
-- Ensures that backspace has the permissions to remove all character types

- Custom Keybindings
- The keybind (Ctrl-e <ARROW KEY>) allows switching between split vim windows 
-- Ctrl-w is the default setting, which closes tabbed shells on Chrome OS

- Backups previous vimrc configurations
-- If they were present, previous vim files are stored in /etc/config-vim/backups/
cloud_user@shaunrd03c:~$ 

Now just open a file in vim to test things out
