run and stop rake task from ruby file

问题

I already know that running a rake task from .rb file can be done by running:

system "/usr/bin/rake #{task} #{args.join(' ')} > #{Rails.root}/log/rake.log"

But how to stop a currently running rake task from ruby file?

Thanks!

回答1:

Perhaps you could do a

ps_aux = system "ps aux | grep #rake_task_name"

then, parse the pid. then, issue a kill command

system "kill #pid"

I haven't tried this yet though.

回答2:

From within the script, you could run the commands suggested by pat (parsing for the pid) in backticks, system or the %x{} wrapper.

回答3:

ps afx | grep rake

Then kill the process id

kill -9 "process_id"
