SC2293 – ShellCheck Wiki

See this page on GitHub


When eval'ing @Q-quoted words, use * rather than @ as the index.

Problematic code:

eval "$MYCOMMAND ${@@Q}"

Correct code:

eval "$MYCOMMAND ${*@Q}"


ShellCheck noticed that you are calling eval and including an escaped array. However, the array is passed as multiple arguments and relies on being implicitly joined together to form a single shell string, which eval can then evaluate.

Instead, prefer building your shell string with explicit string concatenation by using * instead of @ for the index, such as ${*@Q} or ${array[*]@Q}.

This suggestion is equivalent to SC2124, but for eval arguments rather than string variables.
