Redis Utilities
A Node.js based command line interface (CLI) for performing pattern based Redis functions
Installation
$ npm install redis-utils-cli -g
Commands
Copy
Copy keys from one Redis instance to another
Arguments
- <source> The address for the source Redis database (follows this format: [auth@]<hostname>[:port][/db] )
- <destination> The address for the destination Redis database (follows this format: [auth@]<hostname>[:port][/db] )
Options include
- -p <pattern> (Key pattern. Default: *)
- -o (Overwrite. Default (when omitted): false)
- -m <mode> (Hash overwrite mode (key, field). Default: key)
Delete
Delete keys from a Redis instance.
Arguments
- <redis> The address for the Redis database (follows this format: [auth@]<hostname>[:port][/db] )
- <pattern> The key pattern. (Default: *)
List
List all keys and hash fields that match a specified pattern.
Arguments
- <redis> The address for the Redis database (follows this format: [auth@]<hostname>[:port][/db] )
- <pattern> The key pattern. (Default: *)
Count
Display a numeric count of all keys that match a specified pattern.
Arguments
- <redis> The address for the Redis database (follows this format: [auth@]<hostname>[:port][/db] )
- <pattern> The key pattern. (Default: *)
Supported Glob-Style Patterns
h?llomatches hello, hallo and hxlloh*llomatches hllo and heeeelloh[ae]llomatches hello and hallo, but not hilloh[^e]llomatches hallo, hbllo, ... but not helloh[a-b]llomatches hallo and hbllo
Use \ to escape special characters if you want to match them verbatim.
(basically, what you are already familiar with using Redis)
Examples
$ redis-utils copy someauth@10.2.1.44/0 127.0.0.1/0 -p users:*
Copies all keys matching the pattern users:* from 10.2.1.44, db: 0 into 127.0.0.1, db: 0
(Because -o was not included, it would only copy data if the keys do not exist in destination)
For hashes, if you want to copy data based on the existence of hash fields instead of keys, use the -m field option.
$ redis-utils del 127.0.0.1 users:*
Deletes all keys matching the pattern users:* from 127.0.0.1, db: 0
$ redis-utils list 127.0.0.1 users:*
Displays in the terminal, all keys (with some additional details) matching the pattern users:* from 127.0.0.1, db: 0
$ redis-utils count 127.0.0.1 users:*
Displays in the terminal, a numeric count of all keys matching the pattern users:* from 127.0.0.1, db: 0
IMPORTANT NOTE
It is important to note that these commands use the Redis command keys and
by their recommendation, should be used only in production environments with extreme
care as it may ruin performance when executed against large databases.
