SCRIPT LOAD compiles script, stores it in the script cache and returns its SHA1 digest, which you then pass to EVALSHA. Loading the same text again returns the same digest. Scripts loaded this way stay cached until SCRIPT FLUSH or a restart.

Return value

Section titled “Return value”
Case RESP2 RESP3
Compiled Bulk string: the 40-character hexadecimal SHA1 digest Bulk string

Errors:

  • ERR Error compiling script (new function): ... when the script does not compile.
  • ERR Invalid script shebang, ERR Unknown lua shebang option: ... and ERR Unexpected flag in script shebang: ... for a bad shebang line.

Examples
