===========

Redis command-line tools to allow mass export, import and deletion of keys

## Introduction

Redis doesn't come with any tools to allow groups of keys to be imported and exported. You can build a database, save it (as dump.rdb) and use it as another Redis instance's database, but sometimes you just want to export a group of keys from one database (e.g. your staging environment) and apply them to another database (e.g. production).

Requirements:

* PHP with Redis extension

N.B this only works with simple key/value pairs e.g. not hashes or other higher order Redis data types.

## Redis export

This tool exports a group of single key/value pairs to stdout. The output format is the plain text protocol used by Redis e.g.

```

  # export all keys starting with ABC to stdout

  ./redis_export.php "ABC*"  

  

  # export keys with ABC anywhere in the key, to a file

  ./redis_export.php "*ABC* > text.txt

  

  # export all keys to a file

  ./redis_export.php "*" > test.txt

  

```

## Redis import

Data exported using "redis_export.php", can be imported directly into a Redis server:

```

  # apply the data stored in test.txt to the local Redis server

  cat test.txt | ./redis_import.php

```

B.t.w redis_import.php is a one-liner. It basically uses "nc" to pipe the data to the correct port. If you have a modern version of Redis, you can use:

```

  cat test.txt | redis-cli --pipe

```

which will give you feedback of whether your commands worked or not, whereas redis_import.php does not.

## Redis delete

To delete a range of keys:

```

  # delete all keys starting with ABC

  ./redis_delete.php 'ABC*'

```
