Captures command output and appends it to a file.
To start capturing the output of a query, specify the path of the file relative to the current directory. Enclose the file name in single quotation marks. The shorthand notation in this example is supported for referring to $HOME:
Output is not shown on the console while it is captured. Only query result output is captured. Errors and output from cqlsh-only commands still appear.
To stop capturing output and return to normal display of output, use CAPTURE OFF.
To determine the current capture state, use CAPTURE with no arguments.
