Girl Develop It is here to provide affordable and accessible programs to learn software through mentorship and hands-on instruction.
Tell us about yourself.
We'll be using Railsbridge's Installfest instructions to get set up. Railsbridge is an awesome organization that we're friends with and you should be, too!
Just work through the instructions for your operating system. Stop after the "Configure Git" step. Ask a volunteer for help if you get stuck or lost. This process should take about an hour.
Working in the terminal can be really intimidating at first!
With practice, navigation and file manipulation is significantly faster in the terminal than in the GUI.
Professional software developers use the terminal all the time, and this class will require some use of it.
Mac & Linux users: Open Terminal
Windows users: Open Git-Bash
We will not be using Windows "cmd" program, as it uses a different syntax than *NIX systems.
The line that appears in the terminal when you open it is called the prompt. It usually contains information about the user and current directory. It can be customized.
Terminal instructions often start a line with a $. This represents the last character in the prompt, you don't have to type it.
|.||the current directory- ex: "touch ./wow.txt"|
|..||the parent of current directory - ex: "cd ../RubyParty"|
|~||the root directory- ex: "cd ~/Pictures"|
|cd [location]||"change directory" to [location]|
|pwd||"present working directory" - where am I?|
|ls -al||"list all" of the contents of current directory, including invisible ones|
|touch [filename.extension]||create a file called filename.extension in the current directory|
|mkdir [directoryname]||create a directory called directoryname in the current directory|
|rm [filename]||"remove" (delete) the file called filename|
|rm -rf [directoryname]||"remove recursively with force" the directory called directoryname|
|clear OR cmd+k||clear the terminal screen|
|help||lists all possible commands|
|man [command]||displays the manual for command|
# navigate to your desktop cd ~/Desktop #Linux, Mac cd desktop #Windows # make a directory called ruby_adventures mkdir ruby_adventures # navigate into new directory cd ruby_adventures # create a file touch class0.rb # list the contents of the directory ls
Working in the terminal, create a directory called gdi_ruby in the location of your choosing (Desktop? Documents? Somewhere you'll be able to find it again!). Inside the gdi_ruby directory, create a file called class0.txt.
Practice: spend at least 20 minutes practicing navigating and creating/removing documents and directories with the command line.
Learning is more fun with people!
