# Cli R&D
## [Choco/Chocolatey](https://chocolatey.org/)
Chocolatey is a software management solution unlike anything else you've ever experienced on Windows. Chocolatey brings the concepts of true package management to allow you to version things, manage dependencies and installation order, better inventory management, and other features.
- Install Package `choco install pkgname`, adding `-y` will confirm all the prompts : `choco install pkgname -y`
- Checking all commands and flags available : `choco --help`
### Available Commands
* list - lists remote or local packages
* find - searches remote or local packages (alias for search)
* search - searches remote or local packages (alias for list)
* info - retrieves package information. Shorthand for choco search pkgname --exact --verbose
* install - installs packages from various sources
* pin - suppress upgrades for a package
* outdated - retrieves packages that are outdated. Similar to upgrade all --noop
* upgrade - upgrades packages from various sources
* uninstall - uninstalls a package
* pack - packages up a nuspec to a compiled nupkg
* push - pushes a compiled nupkg
* new - generates files necessary for a chocolatey package from a template
* sources - view and configure default sources (alias for source)
* source - view and configure default sources
* config - Retrieve and configure config file settings
* feature - view and configure choco features
* features - view and configure choco features (alias for feature)
* setapikey - retrieves, saves or deletes an apikey for a particular source (alias for apikey)
* apikey - retrieves, saves or deletes an apikey for a particular source
* unpackself - have chocolatey set itself up
* version - [DEPRECATED] will be removed in v1 - use `choco outdated` or `cup <pkg|all> -whatif` instead
* update - [DEPRECATED] RESERVED for future use (you are looking for upgrade, these are not the droids you are looking for)

### Recipes / Containers / Bundles
snap does not have recipes, where the recipe tells what to install as dependencies. rather comes as a bundle containing all it needs.
- Directory `/var/lib/snapd/snaps` generally holds all the bundles (.snap files)
- Each snap runs in its own **containerized sandbox**
- Auto updates
- Larger in size
### Supports
- Linux Distributions
## [Homebrew/brew](https://brew.sh/)
Homebrew is the easiest and most flexible way to install the UNIX tools Apple didn’t include with macOS. It can also install software not packaged for your Linux distribution to your home directory without requiring sudo.
- Install package `brew install pkgname`
- Checking all commands and flags `man brew`
### Basic Commands
```shell=
Example usage:
brew search TEXT|/REGEX/
brew info [FORMULA|CASK...]
brew install FORMULA|CASK...
brew update
brew upgrade [FORMULA|CASK...]
brew uninstall FORMULA|CASK...
brew list [FORMULA|CASK...]
Troubleshooting:
brew config
brew doctor
brew install --verbose --debug FORMULA|CASK

### Supports

## Difference between -arg and --arg
It is a matter of convention. POSIX standard programs usually only have single character options, and they're all prefixed with a single hyphen. The longer versions are a GNU improvement for clarity, as far as I can tell, and usually are prefixed with double hyphens. You can see this in the libraries and programs used to parse options - getopt and gnu-getopt respectively. Non-GNU and non-POSIX-compliant programs may do something else altogether. Note that you really can't be sure that the long form of an argument may be the same from program to program. -f usually means --force, but not with apt-get install (common misconception). -v may mean version - usually, or --verbose, and so on. Check the man pages or other documentation to be sure.
