Apache Cassandra 1.1 Documentation
CAPTURE¶
Captures command output and appends it to a file.
Synopsis¶
CAPTURE ['<file>' | OFF];
Description¶
To start capturing the output of a CQL 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:
Example¶
CAPTURE '~/mydir/myfile.txt';
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.
