How to replace text in a file with text entered
I am trying to write a shell script that will allow the typing of a value, then using that value to replace data in a text file.
I suspect I need sed.

The format of the file is:
Variable1:Value1
Variable2:Value2

The interaction would be something like:
Shell Prompt: "Please enter the value for Variable1: "
User enters: "NewValue"

at which point I'd need to search the text file for Variable1:<ANYTHING> and replace it with Variable1:NewValue

I am barely knowledgeable in sed and RegEx. I tried looking through Sed - An Introduction and Tutorial but I think I'm not quite at that level yet.

Any help is welcome!

Thanks,
Alex
