INDISPENSABLE TOOLS

Fish Screen Mosh

Vagrant



Fish



FISH“Finally, a command line shell for the 90s”

• Color • Web based Config • Auto suggest



SCREEN



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



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



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 ITMac: 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



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 WAY1. 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



THE HARD WAY1. 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 WAY1. Someone new joins your company or team and they need to get their development environment setup 2. Install IDE 3. Install VirtualBox 4. Install Vagrant 5. Clone git repository 6. Run ‘vagrant up’ 7. Make things



MY PROCESS1. New person shows 2. Install VirtualBox 3. Install Vagrant 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



MY PROCESSZero Config for User 1. Apache is using dynamic virtual hosting 2. Local ~/development folder is mapped to /var/www in VM 3. *.dev.emoxie.com points to 192.168.1.50 4. Apache maps the * to /var/www/<*>

WHAT DO I NEED1. Vagrant - vagrantup.com 2. VirtualBox - virtualbox.org 3. PuPHPet - puphpet.com - GREAT Kickstarter to get you going 4. Not a PHP User? http://www.vagrantbox.es

PHP• Not just for the web • $argv[] • get_options()



PHP

<?php var_dump($argv); ?>

php script.php arg1 arg2 arg3

array(4) {! [0]=>! string(10) "script.php"! [1]=>! string(4) "arg1"! [2]=>! string(4) "arg2"! [3]=>! string(4) "arg3"!}



Additional Tools



SEDParses and transforms text !

sed 's/regexp/replacement/g' inputFile > outputFile sed 's/cat/dog/g' inputFile > outputFile

macbook:~ chris$ cat filecatmacbook:~ chris$ sed 's/cat/dog/g' file > dogmacbook:~ chris$ cat dogdog



AWK• Interpreted programming language used for text processing • Great for

!

• length($0) > 80

macbook:~ chris$ ps ax | grep Dropbox | awk '{print $1}'29835



NANO
