When the job is executing in the foreground, for example, directly executing the command trace Test t
, or executing the background job command trace Test t &
, then putting the job back to the foreground via fg command, the console cannot continue to execute other command, but can receive and process the following keyboard events:
ctrl + z
: Suspends the job, the job status will change to Stopped, and the job can be restarted by bg <job-id>
or fg <job-id>
ctrl + c
: Stops the job
ctrl + d
: According to linux semantics this should lead to exit the terminal, right now Arthas has not implemented this yet, therefore simply ignore this keystroke.
