Doing\nthat in perf-record itself, however, is off-limits.\n\nThis patch introduces perf-inject, which does the same job while\nleaving perf-record untouched. Normal mode perf still records the\nbuild-ids at the end of the session as it should, but for live mode,\nperf-inject can be injected in between the record and report steps\ne.g.:\n\nperf record -o - ./hackbench 10 | perf inject -v -b | perf report -v -i -\n\nperf-inject reads a perf-record event stream and repipes it to stdout.\nAt any point the processing code can inject other events into the\nevent stream - in this case build-ids (-b option) are read and\ninjected as needed into the event stream.\n\nBuild-ids are just the first user of perf-inject - potentially\nanything that needs userspace processing to augment the trace stream\nwith additional information could make use of this facility.\n\nCc: Ingo Molnar \u003cmingo@elte.hu\u003e\nCc: Steven Rostedt

checks if the output is a tty, if\nnot it falls back to the previous behaviour, also if\nnewt-devel/libnewt-dev is not installed the previous behaviour\nis maintaned.\n\nPressing enter on a symbol
