SCREEN
•Terminal multiplexer
•Window manager for the terminal
•Has been around since the beginning of time
•Ability to create additional “windows” or terminals within one
terminal window and switch between them

11. Chris Stone | E-Moxie | @cmstone | php[tek] 2014 | Shell Revolution | https://joind.in/10644 11
QUICK START
•screen -R (Reattach a detached session if not already attached)
•screen -ls (List current screen sockets and their state)
•Ctrl+a D (Detach current screen session)
•Ctrl+a C (Create a new window)
•Ctrl+a # (Switch to window)
•Ctrl+a * (List windows)

MOSH - The MObile SHell

13. Chris Stone | E-Moxie | @cmstone | php[tek] 2014 | Shell Revolution | https://joind.in/10644 13
QUICK START
•MIT Computer Science
•Fairly new
•Supports roaming
•Intermittent Connectivity
•Local Echo
•SSH Replacement
•Available for pretty much anything (even iOS and Android)

HOW DO I GET IT
Mac:
brew install mobile-shell
Linux:
apt-get install mosh or yum install mosh
Windows:
Cygwin is experimental

DOWNFALLS OF MOSH
•Not installed by default in most installations
•No terminal scrollback (use screen!)
•Local echo

WHAT IS IT?
•Awesome
•Life changing
•New kid on the block
•The #1 tool you should have in your development arsenal
•Development tool that every developer and project should be
using
•Manager for a virtualization provider (VirtualBox,VMWare, etc)
•Automates your [development] environment (Puppet or Chef)
•Support for Docker containers

18. Chris Stone | E-Moxie | @cmstone | php[tek] 2014 | Shell Revolution | https://joind.in/10644 18
WHY?
•Gets rid of the “it works for me”
•EASY and FAST
•Everyone on the same page
•Closely resembles a production environment
•Keeps your computer clean
•Low barrier to entry

THE HARD WAY
1. Someone new joins your company or team
2.They need to get their development environment setup
3. It takes two days to one week to get up and running
4. Install an IDE
5. Install MAMP or XAMP or something else that can serve pages
6. Make sure the PHP version is the same
7. Make sure the PHP config is the same

20. Chris Stone | E-Moxie | @cmstone | php[tek] 2014 | Shell Revolution | https://joind.in/10644 20
THE HARD WAY
1. Install additional extensions
2. Configure MAMP
3. Always tackle “it works for me” problems in the environment
4. Environment relies on the local machine. Screwed it up? Do it again.
5. Production environment got updated? Let’s make sure everyone
updates to the right version, do it again. Sounds fun....

THE EASY WAY
1. Someone new joins your company or team and they need to get
their development environment setup
2. Install IDE
3. InstallVirtualBox
4. InstallVagrant
5. Clone git repository
6. Run ‘vagrant up’
7. Make things

23. Chris Stone | E-Moxie | @cmstone | php[tek] 2014 | Shell Revolution | https://joind.in/10644 23
MY PROCESS
1. New person shows
2. InstallVirtualBox
3. InstallVagrant
4. Clone git repository
5. Run ‘vagrant up’
6.Vagrant uses puppet to boostrap the system using a very similar
config to production systems
7. Use IDE of choice

24. Chris Stone | E-Moxie | @cmstone | php[tek] 2014 | Shell Revolution | https://joind.in/10644 24
MY PROCESS
Zero Config for User
1. Apache is using dynamic virtual hosting
2. Local ~/development folder is mapped to /var/www inVM
3. *.dev.emoxie.com points to 192.168.1.50
4. Apache maps the * to /var/www/<*>
