Backup script
A fork from backup script.
And refactored.
Execute
./backup.rb
Copy files in ./ori/ to ./target/ .
If there is a file with the same name at target folder, it will skip to next file.
Customize
./backup.rb --from source/ --to target/
Why not just cp -nr source/* target/?
cp is only in unix like systems, in Windows there is a different command.
