# perf\_3.2-inject(1)

Filter to augment the events stream with additional information

## NAME

perf-inject - Filter to augment the events stream with additional information

## SYNOPSIS

```
perf inject <options>
```

## DESCRIPTION

perf-inject reads a perf-record event stream and repipes it to stdout. At any point the processing code can inject other events into the event stream - in this case build-ids (-b option) are read and injected as needed into the event stream.

Build-ids are just the first user of perf-inject - potentially anything that needs userspace processing to augment the events stream with additional information could make use of this facility.

## OPTIONS

\-b, --build-ids=

Inject build-ids into the output stream

- \-v, --verbose

  Be more verbose.
