 # lin-remoteupdate
-Scripts for automatically updating a remote Linux server over SSH.
+These scripts can update multiple remote Linux machines over SSH.
+
+## Prerequisites
+The scripts require sshpass (http://sourceforge.net/projects/sshpass/).
+```
+Ubuntu/Debian: apt-get install sshpass
+Fedora/CentOS: yum install sshpass
+Arch: pacman -S sshpass
+```
+
+## Usage instructions
+1. Download the files to your Linux computer (not the server)
+2. Install the prerequisites (see above)
+2. Enable file execution permissions on local.sh if applicable
+3. Open a terminal and run local.sh
+4. Enter the IP's/Hostnames of the servers you would like to update, seperated by a semicolon (;)
+5. Enter a sudoers account name
+6. Enter the specified account's password
+7. Choose the mode to run in:
+  * 1 = Auto restart when required
+  * 2 = Promt if restart is required
+  * 3 = Ignore (do not restart)
+8. Profit!
+
+## What does it do?
+The local script opens a SSH tunnel to the remote server and does the following:
+sudo apt-get update -y
+sudo apt-get upgrade -y
+sudo apt-get dist-upgrade -y
+sudo apt-get autoremove -y
+sudo apt-get clean
+
+After that the script will check if the machine requires a reboot, depending on your choices when running local.sh it will either automatically restart, prompt for restart or ignore the restart.
