Stock Quote CLI is a Ruby gem that provides a command-line interface for fetching stock information from Yahoo!. It relies on the stock_quote gem for fetching real-time and historical data.

Update: Due to Google's sunsetting of iGoogle (and the associated endpoint from which the stock_quote gem once fetched its data), the stock_quote gem has moved to using the Yahoo! Finance API. This CLI gem has been updated to accommodate the awesomely quick changes.

With Ruby installed, run the following:

gem install stock_quote_cli

You can use Stock Quote CLI to fetch real-time attributes of multiple stocks. Use the stock command in tandem with any of the available subcommands and stock symbols to fetch the relevant attribute(s).

Get historical data for a single stock. The default range is 14 days. The default value is the closing price. These can be specified using the range (aliased to -r) and value (aliased to -v) options, respectively.

stock history fb

The range (-r) option takes an integer. Use this to specify the number of trading days for which you'd like data.

stock history -r 15 fb

The value (-v) option takes a string. Use this to specify the price value that you'd like to see in the output. You can choose from the following:

• open (opening price)
• close (closing price)
• high (high price)
• low (low price)
• volume (share volume)

Below, we fetch the high price for the Facebook stock for the past 15 days.
