To clear the redis terminal, you need to use the flushdb command. This command will remove all keys stored in the current database (default is 0). You can also use the flushall command to clear all keys from all databases. These commands will permanently delete all data stored in the redis instance, so use them with caution.

How to monitor the progress of clearing the redis terminal?
To monitor the progress of clearing the Redis terminal, you can follow these steps:
- Run the FLUSHALL command in the Redis terminal to clear all data in the database.
- Keep an eye on the response from the terminal after running the command. It usually provides a confirmation message indicating that the operation was successful.
- You can also monitor the size of the Redis database before and after running the FLUSHALL command to see if the data has been cleared.
- If you want to monitor the progress in real-time, you can use tools like Redis CLI or a monitoring tool like RedisInsight to view the changes in the database size and monitor the clearing process.
By following these steps, you can effectively monitor the progress of clearing the Redis terminal and ensure that the data has been successfully cleared.
What is the difference between FLUSHDB and FLUSHALL commands in redis?
FLUSHDB command is used to flush the database of the current connection, deleting all keys in the database. This command only affects the database associated with the current connection.
FLUSHALL command is used to flush all the databases in the Redis instance, deleting all keys in all databases. This command affects all databases in the Redis instance, not just the database associated with the current connection.
How to backup data before clearing the redis terminal?
To backup data before clearing the Redis terminal, you can use the following steps:
- Open the Redis CLI terminal by typing redis-cli in the command line.
- Use the SAVE command to create a snapshot of the current data set in Redis. This will save the current data set to a dump.rdb file.
- Copy the dump.rdb file to a safe location on your computer or server. This file contains all the data from your Redis database.
- Once you have backed up the data, you can clear the Redis terminal by using the FLUSHALL command. This will delete all keys from the current database.
By following these steps, you can ensure that you have a backup of your data before clearing the Redis terminal. This will allow you to restore the data if needed in the future.
What is the default behavior of redis when the terminal is cleared?
When the terminal is cleared in Redis, the default behavior is to display the Redis command-line interface prompt, where you can start entering commands to interact with the Redis database. All previously entered commands and their outputs will be cleared from the screen, but the underlying Redis database will not be affected.
What is the recommended frequency for clearing the redis terminal?
There is no specific recommended frequency for clearing the Redis terminal as it depends on the use case and how frequently data is being added or removed from the database. It is a good practice to periodically clear the terminal to ensure optimal performance and to free up memory space. Some users may choose to clear the terminal daily, weekly, or monthly depending on their needs. It is important to monitor the memory usage of the Redis instance and clear the terminal when necessary to prevent any performance issues.
