# Scald.rb¶

The scald.rb script in the scripts/ directory is a handy script that makes it easy to run jobs in both local mode or on a remote Hadoop cluster. It handles simple command-line parsing, and copies over necessary JAR files when running remote jobs.

If you’re running many Scalding jobs, it can be useful to add scald.rb to your path, so that you don’t need to provide the absolute pathname every time. One way of doing this is via (something like):

ln -s scripts/scald.rb $HOME/bin/  This creates a symlink to the scald.rb script in your $HOME/bin/ directory (which should already be included in your PATH).
