 ===== Command =====
-here
+**Command Injection Attacks:** These are attacks that attempt to send commands through a web app to the operating system.
+  * It would give you the ability to directly manipulate the o/s.
+  * On Linux, use the ''system()'' call to send commands to the o/s itself.
+**Example:** If an app asks for a username to set up an account (assuming the username dbag)
+  * When we create our account with the username "dbag," the back-end result sent to the o/s would be something like:
+    * ''system('mkdir /home/dbag')''
+  * Using command injection, you add commands to our user input:
+    * ''dbag & rm -rf /home''
+  * This would result in a command like this:
+    * ''system('mkdir /home/dbag & rm -rf /home')''
+  * And that's bad.
