<ul>
<li class="fragment">"Terminal"</li>
<li class="fragment">"Command-line"</li>
<li class="fragment">"Command prompt"</li>
<li class="fragment">"Shell"</li>
<li class="fragment">"Console"</li>

</section>
<section>
<h2>What is a Terminal?</h2>
<br>
<p>A text-based command interpreter.</p>
<br>
<p>The most common shell is "bash".</p>
<br>
<p>For Mac's OSX, use the "Terminal" application.</p>
</section>
<section>
<h2>Fire it up!</h2>
<p>Windows: Download <a href="https://git-for-windows.github.io/index.html">Git for Bash</a>, then open <code>Git BASH</code></p>
<p>Mac: Open <code>Terminal</code></p>
<img src="img/command-line-blank.png" alt="Black Command Line">
</section>
<section>
<h2>Prompt</h2>
<img src="img/command-line-prompt.png" alt="Command Line prompt">
</section>
<section>
<h2>Prompt</h2>
<br>
<p>Usually shows your username and computer name.</p>
<br>
<p>Indicates that the terminal is ready for a command.</p>
</section>
<section>
<h2>Cursor</h2>
<img src="img/command-line-cursor.png" alt="Command Line cursor">
</section>
<section>
<h2>Cursor</h2>
<br>
<p>Indicates your current spot in the terminal.</p>
<br>
<p>Shows you where the stuff you type will go.</p>
</section>
<section>
<h2>Your First Command</h2>
<br>
<ol>
<li>Type <code>pwd</code> into your terminal.</li>
<li>Press the enter key.</li>
</ol>
</section>
<section>
<h2>Your First Command</h2>
<p><code>pwd</code></p>
<img src="img/command-line-pwd.png" alt="Your first command, pwd">
</section>
<section>
<h2>clear</h2>
<br>
<p>The <code>clear</code> command clears the contents of the terminal and issues a prompt.</p>
<br>
<p>This is good for removing previous output that is unnecessary to the task at hand.</p>
<br>
<p>Feel free to use this whenever things get too cluttered.</p>
</section>
<section>
<h2>Directories</h2>
<br>
<p>Also referred to as "folders".</p>
<br>
<p>A container for files or other directories.</p>
<br>
<p>Nested files and directories can be referenced using <code>paths</code>.</p>
</section>
<section>
<h2>Directory Trees</h2>
<br>
<p>The set of all folders, taken together, makes up your entire file system.</p>
<br>
<p>This system is organized into a kind of upside down tree.</p>
</section>
<section>
<h2>Directory Tress</h2>
<p>At the very top of the tree is the root folder.</p>
<br>
<img src="img/unix-filesystem.png" alt="Unix file directory system">
</section>
<section>
<h2>Paths</h2>
<br>
<p>Each directory or file is separated by a forward slash "/"</p>
<br>
<p>There are two kinds of paths:</p>
<br>
<ul>
<li>Relative: <code>Desktop/the_project/overview.txt</code></li>
<li>Absolute: <code>/Users/jane/Desktop/logo.png</code></li>
</ul>
</section>
<section>
<h2>Shortcuts</h2>
<br>
<ul>
<li>Current Directory: <code>.</code></li>
<li>Parent Directory: <code>..</code></li>
<li>Home Directory: <code>~</code></li>
</ul>
</section>
<section>
<h2>cd</h2>
<br>
<p>The <code>cd</code> command changes the current working directory.</p>
<br>
<p>It expects a file path as an "argument".</p>
<br>
<p>If no file path is given, it assumes your home directory by default.</p>
</section>
<section>
<h2>cd</h2>
<img src="img/command-line-cd.png" alt="Command line cd">
</section>
<section>
<h2>ls</h2>
<br>
<p>The <code>ls</code> command lists the contents of a directory.</p>
<br>
<p>It expects a file path as an "argument".</p>
<br>
<p>If no file path is given, it assumes the current directory by default.</p>
</section>
<section>
<h2>ls</h2>
<img src="img/command-line-ls.png" alt="Command line ls">
</section>
<section>
<h2>Flags</h2>
<br>
<p>The <code>ls</code> command accepts several option flags.</p>
<br>
<p>A flag is a special argument that is used to set an option for the command.</p>
<br>
<p>These are commonly a hyphen followed by a single character (e.g. <code>-g</code>)</p>
<br>
<p>Setting the <code>-l</code> flag on the <code>ls</code> command causes it to provide more verbose output.</p>
</section>
<section>
<h2>ls -l</h2>
<img src="img/command-line-ls-flags.png" alt="Command line ls with flags">
</section>
<section>
<h2>cd & ls</h2>
<br>
<p>Play with the <code>cd</code> and <code>ls</code> commands.</p>
<br>
<h4>Be sure to incorporate:</h4>
<ul>
<li>relative file path</li>
<li>absolute file path</li>
<li>the <code>.</code> shortcut</li>
<li>the <code>..</code> shortcut</li>
<li>the <code>~</code> shortcut</li>
<li><code>cd</code> without an argument</li>
</ul>
<br><br>
<p>Use <code>pwd</code> to check your location periodically.</p>
</section>
<section>
<h2>Making a Directory</h2>
<br>
<p>Use the <code>mkdir</code> command to create a new empty directory.</p>
<br>
<p>Pass the path of the directory name as the first argument.</p>
<br>
<p class="fragment">If the base of the path doesn't already exist, the command will fail.</p>
<br>
<p class="fragment">Use the <code>-p</code> flag to create the full path if non-existent.</p>
</section>
<section>
<h2>mkdir</h2>
<img src="img/command-line-mkdir.png" alt="Command line make directory">
</section>
<section>
<h2>Removing Directories</h2>
<br>
<p>Use the <code>rmdir</code> command to remove an empty directory.</p>
<br>
<p>Use <code>rm -r</code> to remove a non-empty directory.</p>
</section>
<section>
<h2>rmdir</h2>
<img src="img/command-line-rmdir.png" alt="Command line remove directory">

<h2>Let's Develop It!</h2>
<br>
<ol>
<li><code>cd</code> to your home directory.</li>
<li>Create the <code>girl/develop</code> directory path.</li>
<li>Navigate into the <code>girl/develop</code> directory.</li>
<li>Create the <code>it</code> directory.</li>
<li>Navigate up two directories.</li>

<h2>Hidden Files</h2>
<br>
<p>Filenames that begin with a period are hidden from normal output.</p>
<br>
<p>e.g. ".bashrc"</p>
<br>
<p>Use the <code>ls</code> command with the <code>-a</code> flag to see hidden files in addition to the usual output.</p>
<br>
<p>Type <code>ls -la</code> into your terminal.</p>
<br>
<p>Use the <code>-h</code> flag to get human readable file sizes.</p>

<h2>Creating and Removing Files</h2>
<br>
<p>Use <code>touch</code> to create a blank file or update the timestamp on an existing file.</p>
<br>
<p>Use <code>rm</code> to remove files.</p>
</section>
<section>
<h2>Permissions</h2>
<br>
<div class="left-align">
<p>The unix security model breaks up file permissions into three groups:</p>
<br>
<ol>
<li>Owner</li>
<li>Group</li>
<li>Others</li>
</ol>
<br><br>
<table>
<thead>
<tr>
<td>
<h3><code>rwx</code></h3>
</td>
<td>
<h3><code>r-x</code></h3>
</td>
<td>
<h3><code>r-x</code></h3>
</td>
</tr>
</thead>
<tbody>
<tr>
<td>
owner
</td>
<td>
group
</td>
<td>
others
</td>
</tr>
</tbody>
</table>
</div>
</section>
<section>
<h2>Changing Permissions</h2>
<br>
<p>Use <code>chmod</code> to change permissions on a file/directory</p>
<br>
<h4>The argument has three sections:</h4>
<ol>
<li class="fragment"><code>u</code>, <code>g</code>, <code>o</code> to signify which level to target.</li>
<li class="fragment"><code>+</code> or <code>-</code> to indicate whether adding or removing.</li>
<li class="fragment"><code>r</code>, <code>w</code>, <code>x</code> to indicate what type of permission to change.</li>
</ol>
<br><br>
<h4 class="fragment">Examples:</h4>
<p class="fragment"><code>chmod u+w</code> to add write permissions for the file's owner.</p>
<p class="fragment"><code>chmod go-rwx</code> to remove all permissions for the file's group and everyone else.</p>
</section>
<section>
<h2>Let's Develop It!</h2>
<br>
<ol>
<li>Create a new file named <code>testfile</code> in your home directory.</li>
<li>Grant yourself execute permission on the file.</li>
<li>Remove read permission on <code>testfile</code> from your group and everyone else.</li>
<li>Delete <code>testfile</code>.</li>
</ol>

<h2>Standard Output</h2>
<br>
<p>Most commands display their results to a mechanism called the standard output.</p>
<br>
<p>By default, this directs its content to the display.</p>
<br>
<p class="fragment">The standard output can be redirected to a file using the <code>></code> operator.</p>
<br>
<p class="fragment"><code>ls > file_list.txt</code></p>
</section>
<section>
<h2>Standard Output</h2>
<br>
<p>In order to append to the file instead of overwriting it, use the <code>>></code> operator instead.</p>
<br>
<p><code>ls >> file_list.txt</code></p>
<br>
<p class="fragment">Both the <code>></code> and <code>>></code> operator will create the file if it doesn't exist.</p>
</section>
<section>
<h2>Standard Input</h2>
<br>
<p>Whenever commands accept keyboard input, it's likely they are really just drawing input from a mechanism called standard input.</p>
<br>
<p>By default, this is set to keyboard input.</p>
<br>
<p>The input to a command can be redirected to a file by using the <code><</code> operator.</p>
<br>
<p><code>sort < file_list.txt</code></p>
<br>
<p class="fragment">Both input and output can be redirected at the same time.</p>
<br>
<p class="fragment"><code>sort < file_list.txt > sorted_file_list.txt</code></p>
</section>
<section>
<h2>Pipes</h2>
<br>
<p>The "|" character can be used to allow commands to communicate during execution.</p>
<br>
<p>Pipes are placed between commands.</p>
<br>
<p>A pipe will cause the output of the left command to be used as the input of the right command.</p>
<br>
<p><code>ls -l | grep "myfile.txt" du | sort -nr</code></p>
</section>
<section>
<h2>grep</h2>
<br>
<p>The <code>grep</code> command outputs only the lines from a file that match a given pattern.</p>
<br>
<p>This is useful for doing text searches within a file.</p>
<br>
<p>The first argument is the pattern to match. The second, third, and so on are files to search within.</p>
<br>
<p><code>grep "ls" .bash_history</code></p>
<br>
<p class="fragment">If no file argument is given, it
will expect input from the keyboard.</p>
</section>
<section>
<h2>Filters</h2>
<br>
<h4>Filters are commands whose behavior follows the following pattern:</h4>
<ol>
<li>Accept input from standard input.</li>
<li>Perform some operation on it.</li>
<li>Send the results to standard output.</li>
</ol>
</section>
<section>
<h2>Filters</h2>
<p>Check out the man pages for the following:</p>
<br>
<p><code>sort</code></p>
<p><code>uniq</code></p>
<p><code>grep</code></p>
<p><code>head</code></p>
<p><code>tail</code></p>
<p><code>fmt</code></p>
<p><code>pr</code></p>
<p><code>tr</code></p>
<p><code>sed</code></p>
<p><code>awk</code></p>
</section>

<h2>Let's Develop It!</h2>
<br>
<p>Use the <code>ls</code> and <code>grep</code> commands to print out only the files in your home directory that contain the word "bash".</p>
</section>

<h2>Processes</h2>
<br>
<p>Whenever a command is executed, a new process is created.</p>
</section>
<section>
<h2>top</h2>
<br>
<p>The <code>top</code> command provides an up-to-date feed of information on the most active processes across the machine.</p>
<br>
<p>Useful for finding processes that are hogging the CPU.</p>
</section>
<section>
<h2>ps</h2>
<br>
<p>The <code>ps</code> utility displays all of your processes that have controlling terminals.</p>
</section>
<section>
<h2>ps</h2>

</section>
<section>
<h2>Key Sequences</h2>
<br>
<p><code>Ctrl + Z</code>: Suspend the current process</p>
<br>
<p><code>Ctrl + C</code>: Terminate the current process</p>
</section>
<section>
<h2>Suspending a Process</h2>
<img src="img/command-line-suspend-process.png" alt="Command Line suspending a process">
</section>
<section>
<h2>bg & fg</h2>
<br>
<p>The <code>bg</code> and <code>fg</code> commands bring a suspended process back into a running state.</p>
<br>
<p><code>bg</code> runs it in a background process.</p>
<br>
<p><code>fg</code> runs it in the foreground of the current terminal.</p>
<br>
<p class="fragment">By default they target the most recently suspended process.</p>
<br>
<p class="fragment">The job number can be provided as an argument. (The number we saw when we suspended the process)</p>
</section>
<section>
<h2>Let's Develop It!</h2>
<br>
<ol>
<li>Run the <code>top</code> command.</li>
<li>Suspend the process.</li>
<li>Bring the process back into the foreground.</li>
</ol>

<h2>kill</h2>
<br>
<p>The <code>kill</code> command terminates or sends a signal to a process.</p>
<br>
<p>It takes the process id (PID) as an argument.</p>
<br>
<p>You can find the PID using <code>top</code> or <code>ps</code>.</p>
</section>
<section>
<h2>Let's Develop It!</h2>
<br>
<ol>
<li>Clear your terminal and run the <code>yes</code> command.</li>
<li>Use the <code>Ctrl+Z</code> key sequence to suspend the process.</li>
<li>Use the <code>bg</code> command to send the process to the background.</li>
<li>Notice the output is still happening even though the process is running in the background.</li>
<li>Open a new terminal window, locate the PID for the "yes" process and use it to kill the process.</li>
</ol>
</section>
<section>
<h2>Commands</h2>
<br>
<p>Typing <code>!</code> followed by the name of a command will repeat the last line that began with that command.</p>
<br>
<ul>
<li><code>ls -la ~ | grep "Desktop"</code></li>
<li><code>!ls</code></li>
</ul>
<br><br>
<p>In both instances, you should get the same output because the second line is simply repeating the first.</p>
<br>
<p>Typing <code>!!</code> by itself will re-run the last line entered.</p>
</section>
<section>
<h2>history</h2>
<br>
<p>The terminal keeps an ongoing log of all the commands you've run.</p>
<br>
<p>The <code>history</code> command prints the contents of the history file.</p>
</section>
<section>
<h2>history</h2>
<img src="img/command-line-history.png" alt="Command Line history">
</section>
<section>
<h2>history</h2>
<br>
<p>You can run a previous command using the number in the history.</p>
<br>
<p><code>!12</code></p>
<br>
<p class="fragment">Almost no one does this.</p>
</section>
<section>
<h2>Keyboard Shortcuts</h2>
<br>
<p><code>Ctrl + a</code> moves the cursor to the beginning of the command.</p>
<br>
<p><code>Ctrl + e</code> moves the cursor to the end of the command.</p>
<br>
<p>Use the <code>tab</code> key to auto complete file paths</p>
<br>
<p>Use the <code>up</code> arrow to cycle through the command history.</p>
</section>
<section>
<h2>Let's Develop It!</h2>
<br>
<ol>
<li>Use your <code>up</code> and <code>down</code> arrows to locate a past command with one or more arguments.</li>
<li>Move your cursor to the beginning of the line.</li>
<li>Move your cursor to the end of the line.</li>
<li>Change one of the arguments and run it.</li>
<li>Run the <code>date</code> command.</li>
<li>Re-run the command from step 4 using <code>!</code>.</li>
<li>Time the execution of your original command by running <code>time !!</code>.</li>
</ol>
</section>
