Printf + Cat function

Question

I'm currently working with Neo4j.

I want to launch a cypher script via my terminal but I would like to set parameter before launching my script.

Here my statement,

>printf ':param test=>'value' \n' | cat file.cypher | cypher-shell -a bolt:server -u user-p pwd --format=verbose --fail-at-end --non-interactive --debug

Output :

>org.neo4j.driver.v1.exceptions.ClientException: Expected parameter(s): test

So I have the feeling my printf quote is not read.

Is there anybody already worked with the combination of printf and cat ?

Thank you in advance,

G.

The Cypher Shell tool has command-line options for specifying parameter values (--param) and input files (-f). You do not need to use pipes.

For example:

./cypher-shell -u user -p pwd -f file.cypher --param "test=>'value'"
