I have installed a new module called S3fs using Composer. When I try to execute /root/.composer/vendor/bin/drush drush_s3fs_copy_local, it shows the following error.

Command "drush_s3fs_copy_local" is not defined

I found out that I could not run any command from third-party modules I installed and enabled.

Please help me.

drush_s3fs_copy_local is the name of the PHP callback function for the command; the command itself is named s3fs-copy-local, with an alias of s3fs-cl.


drush s3fs-cl

Is what you're looking for.

  • yeah i tried this it didn't work.s3fs module is enabled. my drush version is 9.5.2 and drupal is 8.6.4.
