@yohamta hi , can i try to work on this issue ?

@yohamta I have found some problems,when i work on this issue In this issue requirements :  in [/dag/scheduler/node.go](https://github.com/daguflow/dagu/blob/main/internal/dag/scheduler/node.go#L152)  [uitil.SplitCommandWithParse() function](https://github.com/daguflow/dagu/blob/main/internal/util/utils.go#L92)  the `os.ExpandEnv()` Will replace the string `${DAG_REQUEST_ID}`...

@yohamta If the main scenario for this feature is to print the corresponding variables through a command execution, should other executors besides command be added?

Hi @yohamta I believe this is an excellent solution! I'll start working on it. Thank you! Your help has been invaluable.
