Regex match all words including slash

Question

I would like to remove all words behind the number.

12 - Balloon Cool
1 - I would like to sleep
541 - Sleep is for weak/sheep

Currently I 'm using this regex to replace them with empty

/ - (\w+( +\w+)*)/

It managed to filter some but not for the string with slash.

Answer 1

To remove any thing after space-hyphen-space you can just use:

/ - .*$/m
