Watch This Run Repeatedly

I usually reach for a quick bash for loop when I want to run a particular process a bunch of times in a row. The watch command is another way to run a process repeatedly.

watch rspec spec/some/test.rb

The default is 2 seconds in between subsequent executions of the command. The period can be changed with the -n flag though:

watch -n 2 rspec spec/some/test.rb
