# REDIS-BASH - Bash library to access Redis Databases
[](https://github.com/caquino/redis-bash/actions/workflows/release.yml)
* The library comes with two examples, one generic client and a pubsub demo.
* This library has no external dependencies, using only bash built-in commands.
* The only requirement is bash to have net redirections enabled.
* The command validation is made by the server.
## Using the client and the pubsub demo
### Client
```bash
$ redis-bash-cli
```
Parameters:
```
-h Host - Defaults localhost.
-p Port - Defaults 6379.
-n DB - Select the database DB.
-r N - Repeat command N times.
-a PASSWORD - Authentication password
-i INTERVAL - Interval between commands
```
Examples:
```bash
$ redis-bash-cli -h localhost SET testkey 1234
OK
$ redis-bash-cli -h localhost GET testkey
1234
$ redis-bash-cli -h localhost PING
PONG
$ redis-bash-cli -h localhost -r 5 PING
PONG
PONG
PONG
PONG
PONG
$ redis-bash-cli -h localhost WRONGCOMMAND test
ERR unknown command 'WRONGCOMMAND'
```
Authenticated requests:
```bash
$ redis-bash-cli -h localhost PING
ERR operation not permitted
$ redis-bash-cli -h localhost -a test PING
PONG
```
### Pubsub
```bash
$ redis-pubsub-test
```
Parameters:
```bash
-h Host - Defaults localhost.
-p Port - Defaults 6379.
CHANNEL - Channel to subscribe
```
## Pubsub demo
In one shell run the command:
```bash
$ redis-pubsub-test test
```
In another shell run the command:
```bash
$ redis-bash-cli -h localhost -p 6379 PUBLISH test "Hello World."
```
# Using the Library in your code
The library have a single function to handle the redis communication.
```bash
$ redis-client
```
* FD: file descriptor to access the redis database
* COMMAND: command to be sent to the server, can be blank to do read operation.
Using the library:
```bash
#!/bin/bash
source redis-bash-lib # include the library
exec 6<>/dev/tcp/localhost/6379 # open the connection
redis-client 6 SET test 1234 # do a SET operation
exec 6>&- # close the connection
```

# TESTED
* Debian squeeze 6.0.X - GNU bash, version 4.1.5(1)-release (x86_64-pc-linux-gnu)
* Mac OS X Lion 10.7.X - GNU bash, version 3.2.48(1)-release (x86_64-apple-darwin11)
# PERFORMANCE
This test has no intent to be a complete benchmark, but only to show the diference between both clients.
```bash
$ time redis-bash-cli -h 192.168.86.1 -r 10 PING > /dev/null
