NAME
neo4j-client - command shell for Neo4j
SYNOPSIS
neo4j-client [options...] [URL | host[:port]]
DESCRIPTION
neo4j-client is a command shell for Neo4j. It supports secure connections to Neo4j server, sending of
statements (including multiline statements), persistent command history, and rendering of results to
tables or CSV.
neo4j-client requires Neo4j Server version 3.0 or later.
OPTIONS
--help, -h
Display a brief help listing.
--history=file
Use the specified file for saving history.
By default, history is saved to $(HOME)/.neo4j/client-history.
--no-history
Do not save the command history.
--colorize
Enable colorization of output and errors using ANSI escape sequences.
--no-colorize
Disable colorization of output and errors even when connected to a TTY.
--ca-file=cert.pem
Specify a file containing trusted certificates (and CRLs). The file should contain one or more
certificates in PEM format.
--ca-directory=dir
Specify a directory containing trusted certificates (and CRLs). The certificates should have names
of the form: hash.0 or have symbolic links to them of this form ("hash" is the hashed certificate
subject name: see the -hash option of the x509 utility). Under Unix the c_rehash script will
automatically create symbolic links to a directory of certificates.
--insecure
Do not attempt to establish a secure (TLS) connection to Neo4j.
--non-interactive
Use non-interactive (batch) mode and do not prompt for credentials when connecting.
--username=name, -u name
Use the specified username when connecting.
The username (and password) can also be supplied in the connection URL, and will override what is
set here.
--password=pass, -p pass
Use the specified password when connecting.
The password (and username) can also be supplied in the connection URL, and will override what is
set here.
-P Prompt for a password, even in non-interactive (batch) mode. This option requires that neo4j-
client is being run with a controlling TTY, which will be used for password prompting and input.
--known-hosts=file
When using secure (TLS) connections, the certificate signatures of previously verified hosts is
persisted to the known hosts file. This setting specifies the location of that file.
By default, the file is $(HOME)/.neo4j/neo4j_known_certs.
--no-known-hosts
Do not do host checking via known-hosts (use only TLS certificate verification).
--output file, -o file
Redirect output to the specified file. Must be specified in conjunction with --source/-i, and may
be specified multiple times.
--source file, -i file
Evaluate statements from the specified file. May be specified multiple times.
--eval script, -e script
Evaluate the argument string. May be specified multiple times.
--verbose, -v
Increase the logging verbosity. Each use increases the verbosity. Each verbosity level roughly
equates to logging of warnings, general information, debug output and trace information.
--version
Print the neo4j-client version and exit.
URL
A URL may be specified on the command line, and will cause neo4j-client to attempt to connect to the
specified server immediately. The URL is of the form neo4j://host[:port], and specifies the host and port
the Neo4j server is listening on.
INTERACTIVE MODE
When neo4j-client is started with standard input connected to an interactive terminal, it will run in
interactive mode. This will present a command prompt to the user and will evaluate each command as it is
entered. The history of entered commands will be saved (unless disabled) and an errors in evaluation will
be presented to the user. Results from statements sent to Neo4j will be presented to the user in table
format (by default), using the full width of the terminal.
NON-INTERACTIVE (BATCH) MODE
When neo4j-client is started with standard intput connected to a pipe, or when the --source/-i argument
is specified, statements will be read from the pipe or the specified file(s). Any error in evaluation
will cause neo4j-client to terminate without evaluating any further input. By default, results will be
output in CSV format, although this may be changed using :set format=(csv|table).
USAGE
Once started, commands and statements can be entered at the neo4j-client prompt. Commands always begin
with a colon (:) and conclude at the end of the line, e.g. :help, and are evaluated by neo4j-client
rather than being sent to the Neo4j server. Statements do not begin with a colon (:), may span multiple
lines, are terminated with a semi-colon (;) and will be sent to the Neo4j server for evaluation.
COMMANDS
neo4j-client understands a variety of commands, including:
:help List all the available commands and usage information.
:quit (or :exit)
Exit neo4j-client.
:connect '<url>'
Connect to the Neo4j server specified by the URL. Note that the URL must be given in quotes, as
the // characters in the URL would otherwise be considered as the start of a comment.
:connect <host>[:<port>]
Connect to the Neo4j server specified by the host and optional port.
:disconnect
Disconnect from the Neo4j server (if connected).
:export [name=val] ...
Export parameters for queries. The parameter will be available in queries as {name}, and will be a
string containing the text specified. Values containing spaces must be quoted, e.g. :export
name="foo bar". Multiple name and value pairs may be specified. If no name and value pairs are
specified, then the list of currently exported values will be displayed.
Note that all parameters are sent to the server for every query, so it is best not to export large
values without immediately using :unexport after.
:unexport name ...
Remove a named parameter from those exported to queries.
:reset Reset the session with the server, aborting any open transactions.
:set [option=value] ...
Set various shell options. If no option name and value paris are specified, then the list of
current options and their values will be displayed.
:source <file>
Read and evaluate commands and statements in the specified file. Evaluation will stop if any error
is encountered.
:status
Show the client connection status, which indicates if the client is disconnected or connected to a
server. If the latter, the connection URI is output.
:schema
Show database schema indexes and constraints.
:format (table|csv)
Set the output format to either table or CSV.
Equivalent to `:set format=(table|csv)`.
:width <n>
Set the output width for table rendering. n is either an integer between 2 and 4095, or "auto". In
interactive mode, the default is "auto", which sets the output width to match the width of the
terminal (or to 70 characters if the output is not a terminal).
Equivalent to `:set width=<n>`.
EXAMPLES
Start neo4j-client in interactive mode, and run a query:
$ neo4j-client -u neo4j localhost
Password: *****
neo4j> MATCH (n:Person) RETURN n.name, n.born LIMIT 4;
+-----------------------------+-----------------------------+
| n.name | n.born |
+-----------------------------+-----------------------------+
| Keanu Reeves | 1964 |
| Carrie-Anne Moss | 1967 |
| Laurence Fishburne | 1961 |
| Hugo Weaving | 1960 |
+-----------------------------+-----------------------------+
neo4j> :quit
$
Evaluate a query in non-interactive (batch) mode, saving the output to a csv file:
$ echo "MATCH (n:Person) RETURN n.name, n.born LIMIT 4;" | \
neo4j-client -u neo4j -P localhost > result.csv
Password: *****
$
$ cat result.csv
"n.name","n.born"
"Keanu Reeves",1964
"Carrie-Anne Moss",1967
"Laurence Fishburne",1961
"Hugo Weaving",1960
$
Evaluate a source file, and save the output:
$ neo4j-client -u neo4j -p pass -o result.csv -i query.cyp
$
$ cat query.cyp
MATCH (n:Person) RETURN n.name, n.born LIMIT 4;
$
$ cat result.csv
"n.name","n.born"
"Keanu Reeves",1964
"Carrie-Anne Moss",1967
"Laurence Fishburne",1961
"Hugo Weaving",1960
$
ERRORS
In interactive mode, neo4j-client attempts to exit cleanly (with $? set to 0) when the session is
terminated via the use of :quit, :exit or ctrl-D, and to use a non-zero exit code otherwise. In non-
interactive (batch) mode, neo4j-client will exit cleanly if all statements read from stdin evaluate
successfully.
