31.1. Starting the shell
When used together with a Neo4j server, simply issue the following at the command line:
For help with running shell using Windows PowerShell, see Section 23.3, “Windows PowerShell module”.
For the full list of options, see the reference in the Shell manual page.
You need to make sure that the shell jar file is on the classpath when you start up your Neo4j instance.
Enabling the shell server
Shell is enabled from the main configuration of Neo4j, see Section 24.8, “Configuration Settings Reference”. Here’s the available settings:
Settings for the remote shell extension
Enable a remote shell server which Neo4j Shell clients can log in to.
Remote host for shell. By default, the shell server listens only on the loopback interface, but you can specify the IP address of any network interface or use
The name of the shell.
The port the shell will listen on.
Read only mode. Will only allow read operations.
There are two ways to start the shell, either by connecting to a remote shell server or by pointing it to a Neo4j store path.
Connecting to a shell server
To start the shell and connect to a running server, run:
-name options depending on how the remote shell server was enabled.
Then you’ll get the shell prompt like this:
Pointing the shell to a path
To start the shell by just pointing it to a Neo4j store path you run the shell jar file. Given that the right neo4j-kernel-<version>.jar and jta jar files are in the same path as your neo4j-shell-<version>.jar file you run it with:
$ neo4j-shell -path path/to/neo4j-db
By issuing the
-readonly switch when starting the shell with a store path,
changes cannot be made to the database during the session.
$ neo4j-shell -readonly -path path/to/neo4j-db
Run a command and then exit
It is possible to tell the shell to just start, execute a command and then exit.
This opens up for uses of background jobs and also handling of huge output of f.ex. an
ls command where you then could pipe the output to
less or another reader of your choice, or even to a file.
And even to another neo4j-shell, e.g. for importing a
dump of another database or cypher result. When used with command mode the shell will not output a welcome message.
So some examples of usage:
$ neo4j-shell -c "cd -a 24 && set name Mattias" $ neo4j-shell -c "trav -r KNOWS" | less
Pass Neo4j configuration options
By setting the
-config switch, you can provide a properties file that will be used to configure your Neo4j instance,
if started in embedded mode.
$ neo4j-shell -config conf/neo4j.properties -path mydb
Execute a file and then exit
To execute commands from a file and then exit just provide a
filename. This is faster than piping to the shell which still handles
the input as if it was user input.
For example reading a dump file directly from the command line and executing it against the given database. For example:
$ neo4j-shell -file export.cql > result.txt
- as the filename reads from
