Very handy SVN 'sync' script

This is a script i practically use all the time. I think its kind of genius, do you? Please give feedback and critique! :pinguin:

Here is my scenario:
I have a workstation at home and a laptop for school. I also have headless server, made from an historical HP Pavilion workstation.
Since i use my laptop every day at school, i need to get my projects over to my workstation so i can keep on working when i come home. Thats where my server comes in. I just run 'sync' on my laptop and it updates the project through svn repositories at the server. I can then sync the workstation and VIOLA!

exit 0

Run by:


sync all

sync -c all

sync -bdp

Ive made the code generic so you dont have to make a lot of changes if you what to add/remove a repository.
You can also run the script on the server, though this is not thoroughly testet. See # Set host.
To use the keyless SSH implementation see links at bottom. (Its awesome...)

Other remarks:

You can sync all repositories with the 'all' option.
You can commit all and skip the prompt with the '-c' option.
It features getopts for easy option handling.
It features SSH for safe data transfers.

The getYn file is included below.

#!/bin/bash


# Function get yes or no with custom prompt

# By 7SLEVIN


getYn ()

{

prompt="$1"

while true

do

	read -p "$prompt" yn

	case $yn in

		[Yy]* ) ans=true;break;;

		[Nn]* ) ans=false;break;;

		* ) ;;

	esac

done

echo $ans

}
