Unrecognized option or bad number of args for: '--evalsha'

When I run redis-cli script load "$(cat ./scripts/restoreSymbols.lua)" for the following script:

local list = {}
local result = redis.call('scan', 0, 'MATCH', 'symbol:*', 'COUNT', 1000)
for _, v in ipairs(result[2]) do
    list[#list+1] = redis.call('hgetall', v)
end
return list

I get a sha a8a6b471abf42b6cc584444e9d269e9807d96ff1 but when I then run redis-cli --evalsha a8a6b471abf42b6cc584444e9d269e9807d96ff1 I get:

Unrecognized option or bad number of args for: '--evalsha'

How is this possible? I don't need any options or arguments. The script is working (debugged it with the debugger) and also runs when I normal --eval it.

Solution

  • The --evalsha flag is not a valid redis-cli option. You can use --eval to run your script like 

    redis-cli --eval ./scripts/restoreSymbols.lua

    But if you want to use evalsha to run a loaded script, what you need to do is

    redis-cli evalsha a8a6b471abf42b6cc584444e9d269e9807d96ff1 0

    Note that you have to pass the 0 to indicate that you are not passing any argument to the command.
