# 4.1. Overview

1
The idstore package provides a command-line interface for performing tasks such as starting the server, checking configuration files, hashing passwords, and etc. The base idstore command is broken into a number of subcommands which are documented over the following sections.

### 4.1.2. Command-Line Overview

    Usage: idstore [options] [command] [command options]

      Options:
        --verbose
          Set the minimum logging verbosity level.
          Default: info
          Possible Values: [trace, debug, info, warn, error]

      Use the "help" command to examine specific commands:

        $ idstore help help.

      Command-line arguments can be placed one per line into a file, and the file
      can be referenced using the @ symbol:

        $ echo help > file.txt
        $ echo help >> file.txt
        $ idstore @file.txt

      Commands:
        help           Show detailed help messages for commands.
        initialize     Initialize the database.
        server         Start the server.
        version        Retrieve the version number.

All subcommands accept a --verbose parameter that may be set to one of trace, debug, info, warn, or error. This parameter sets the lower bound for the severity of messages that will be logged. For example, at debug verbosity, only messages of severity debug and above will be logged. Setting the verbosity to trace level effectively causes everything to be logged, and will produce large volumes of debugging output.
4
The idstore command-line tool uses jcommander to parse command-line arguments, and therefore supports placing command-line arguments into a file, one argument per line, and then referencing that file with @. For example:

### 4.1.5. @ Syntax

    $ idstore server --configuration server.conf

    $ (cat <<EOF
    --configuration
    server.conf
    EOF
    ) > args.txt

    $ idstore @args.txt

6
All subcommands, unless otherwise specified, yield an exit code of 0 on success, and a non-zero exit code on failure.
