On a test instance,
drush watchdog-show shows, among three other entries, a message starting with "Notice: Undefined property:". However, both of the following commands print nothing at all:
drush watchdog-show "Notice" drush watchdog-show "Undefined property"
drush watchdog-show ":" does print the message, but also other irrelevant message. So how do I search watchdog messages like it says in the documentation:
drush watchdog-show "cron run succesful" Show a listing of most recent 10 messages containing the string "cron run succesful".
