I can't add option "-v" to console symfony

Question

I want to add a command to my application console,

I can't add "-v" option to my code with ->addOption to run my command console on symfony.

When i run the command with bin/console app:cmd:name [option], an error appear:

An option with shortcut "v" already exists.

Answer 1

The -v or -vv or -vvv is a reserved "command shortcut" in Symfony to increase the verbosity of messages:

1 "-v" for normal output

2 "-vv" for more verbose output

3 "-vvv" for debug

So you have to use another shortcut for your command.

Also, you can take a closer look at the Symfony verbosity levels: Verbosity levels documentation
