The \fs [name] command will save the current statement with a name.
The \f [name] command will load the statement with that name or list all the saved statements if no name is given.
The \fd [name] command will delete the saved statement.

Exit the CLI app with exit, quit or \q.
If you see this error message make sure that the $ORACLE_HOME/lib is on $LD_LIBRARY_PATH. This is needed by cx-oracle to make the database connection. As a sanity check ls $ORACLE_HOME/lib should list the oracle libraries.
Update the library-path with:
export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:$ORACLE_HOME/lib
In principle okcli should work on Windows but it has only been tested on Linux. If you're interested in testing on Windows please raise an issue.
Thanks to mycli. Most of the features (e.g. syntax highlighting, auto-complete) were implemented by the mycli core team for MySQL.
