像这样从命令行启动乐器之后
instruments -v -t "Counters" -l 1000 /path/to/exec --args
我得到了输出
instruments : 1000ms time limit specified
instruments[98475]: Loading template 'file:///Applications/Xcode.app/Contents/Applications/Instruments.app/Contents/Resources/templates/Counters.tracetemplate'
instruments[98475]: Preparing To Start Trace
instruments[98475]: Starting Recording
instruments[98475]: Stopping Recording
但是instruments进程永远不会终止。我怎样才能使其自动终止？
