Shell Scripting

Linux shell scripting. A script is a sequence of shell commands

Example

 * 1) !/bin/bash

if grep immanuelle /etc/passwd > /dev/null

then

echo "Hello World!"

fi

echo "Done

Explanation
```#!/bin/bash``` determined that the shell is using Bash which is important for a script file which may be opened when using a different shell scripting language (terminology right?) The if follows from a command successfully executing indentation for readability but it is not technically necessary fi is the end of an if statement (if backwards)

Commands

 * x=7 lets you define a variable locally
 * test
