The <info>%command.name%</info> command displays all configured <comment>public</comment> services:

  <info>php %command.full_name%</info>

To see deprecations generated during container compilation and cache warmup, use the <info>--deprecations</info> option:

  <info>php %command.full_name% --deprecations</info>

To get specific information about a service, specify its name:

  <info>php %command.full_name% validator</info>

To get specific information about a service including all its arguments, use the <info>--show-arguments</info> flag:

  <info>php %command.full_name% validator --show-arguments</info>

To see available types that can be used for autowiring, use the <info>--types</info> flag:

  <info>php %command.full_name% --types</info>

To see environment variables used by the container, use the <info>--env-vars</info> flag:

  <info>php %command.full_name% --env-vars</info>

Display a specific environment variable by specifying its name with the <info>--env-var</info> option:

  <info>php %command.full_name% --env-var=APP_ENV</info>

Use the --tags option to display tagged <comment>public</comment> services grouped by tag:

  <info>php %command.full_name% --tags</info>

Find all services with a specific tag by specifying the tag name with the <info>--tag</info> option:

  <info>php %command.full_name% --tag=form.type</info>

Use the <info>--parameters</info> option to display all parameters:

  <info>php %command.full_name% --parameters</info>

Display a specific parameter by specifying its name with the <info>--parameter</info> option:

  <info>php %command.full_name% --parameter=kernel.debug</info>

By default, internal services are hidden. You can display them
using the <info>--show-hidden</info> flag:

  <info>php %command.full_name% --show-hidden</info>
