## dlv trace

Compile and begin tracing program.

### Synopsis

7 8 9 10 11 12
Trace program execution.

The trace sub command will set a tracepoint on every function matching the
provided regular expression and output information when tracepoint is hit.  This
is useful if you do not want to begin an entire debug session, but merely want
to know what functions your process is executing.

The output of the trace sub command is printed to stderr, so if you would like to
only see the output of the trace operations you can redirect stdout.
