drupal 8 - Drush doesn't export command result as file

Question

I would to export result from a command run by drush but it doesn't work. This command create an empty file:

drush @sited8bl.preprod ms > ~/www/XXX/exports-bruts/$(date +%Y%m%d_%H%M%S)-migrationsBL.txt --debug

This debug message let think the command isn't found:

[debug] Done with bootstrap max in Application::find(): trying to find ms again. [4.39 sec, 31.8 MB]

On another server (multisite) it works, the hosting say there is a drush issue. If someone can help me on this

Thanks
