Raw

A pure Go Redis-cli

Go Report Card

This is a simple redis-cli forked from https://github.com/siddontang/ledisdb(ledis-cli). Fully compatible with Redis Protocol specification.

Features

  • Pure Go implementation
  • Full compatible with Redis Protocol specification
  • Basic support for hostname, port, auth, db
  • REPL
  • Non-interactively execute command
  • Raw format output
  • Monitor command support (both in REPL and execution directly)
  • CONNECT command support(example is as follows)

Install

To install, use go get

go get -u -v github.com/holys/redis-cli

or download binary file from release.

Usage

$ ./redis-cli --help
Usage of ./redis-cli:
  -a string
        Password to use when connecting to the server
  -h string
        Server hostname (default "127.0.0.1")
  -n int
        Database number(default 0)
  -p int
        Server server port (default 6379)
  -raw
        Use raw formatting for replies
  -s string
        Server socket. (overwrites hostname and port)

Almost the same as the official redis-cli.

$ ./redis-cli
127.0.0.1:6379> get info
"{\"age\":1,\"name\":\"cdh\"}"

$ ./redis-cli --raw
127.0.0.1:6379> get info
{"age":1,"name":"cdh"}

$ ./redis-cli get info
"{\"age\":1,\"name\":\"cdh\"}"

$ ./redis-cli --raw get info
{"age":1,"name":"cdh"}

$ ./redis-cli monitor

New command support: CONNECT host port [auth]

$ ./redis-cli
127.0.0.1:6379> set hostport "127.0.0.1:6379"
OK
127.0.0.1:6379> get hostport
"127.0.0.1:6379"
127.0.0.1:6379> connect 127.0.0.1 6380
connected 127.0.0.1:6380 successfully
127.0.0.1:6380> get hostport
(nil)
127.0.0.1:6380>

Play with GoTTY

gotty -w ./redis-cli --welcome

Why I build this?

Sometimes I would like to access to the redis-server(or redis-proxy), but there is no redis-cli in the the production machine which is controlled by the ops guys, and I don't have the root privilege to install one via apt-get or yum. Some people may ask that why don't you ask the ops guys for help? I just don't want to bother them because somtimes they are very busy, and I just want the redis-cli for single use. People may be curious that why don't I git clone one from github and build it from source.

Ok, let me show you:

git clone https://github.com/antirez/redis.git

remote: Counting objects: 45784, done.
remote: Compressing objects: 100% (92/92), done.

Receiving objects:   2% (1242/45784), 300.01 KiB | 7 KiB/s

The network condition really drives me crazy.

People who has C/C++ backrground must know that you can't simply copy a linux executable file from one machine to another and make it run successfully, because sometimes the target machine lacks of the matched glibc or other .so files.

$ ldd redis-cli
    linux-vdso.so.1 =>  (0x00007fffe93fe000)
    libm.so.6 => /lib/x86_64-linux-gnu/libm.so.6 (0x00007f17ff5f9000)
    libpthread.so.0 => /lib/x86_64-linux-gnu/libpthread.so.0 (0x00007f17ff3db000)
    libc.so.6 => /lib/x86_64-linux-gnu/libc.so.6 (0x00007f17ff015000)
    /lib64/ld-linux-x86-64.so.2 (0x00007f17ff919000)

So I just want a pure go solution，build once, and run everywhere(aha Java).

Please correct me if I am wrong.
