What were you trying? seems to work for me:
```text
$ cat x.groovy
println "123"
$ bin/gremlin.sh -e x.groovy
123
$ bin/gremlin.sh -e=x.groovy
123
$ bin/gremlin.sh -i=x.groovy
\,,,/
(o o)
-----oOOo-(3)-oOOo-----
plugin activated: tinkerpop.server
plugin activated: tinkerpop.utilities
plugin activated: tinkerpop.tinkergraph
123
gremlin> :x
$ bin/gremlin.sh --interactive=x.groovy
\,,,/
(o o)

$ bin/gremlin.sh --execute=x.groovy
