Custom fields set for each type by prepending field argument with type.
For file with multiple event types (e.g., trace and S/W) display of an
event type suppressed by setting output fields to "".
e.g.,
perf record -ga -e sched:sched_switch -e cpu-clock -c 10000000 -R -- sleep 1

To suppress trace events within the file and use default output for S/W events:
perf script -f trace:
or to suppress S/W events and do default display for trace events:
perf script -f sw:
Custom field selections:
perf script -f sw:comm,tid,time -f trace:time,trace

Allow a user to select which fields to print to stdout for event data.
Options include comm (command name), tid (thread id), pid (process id),
time (perf timestamp), cpu, event (for event name), and trace (for
trace data).
Default is set to maintain compatibility with current output; this
feature does alter output format slightly -- no '-' between command
and pid/tid.
Thanks to Frederic Weisbecker for detailed suggestions on this approach.
Examples (output compressed)
1. trace, default format
perf record -ga -e sched:sched_switch
perf script
swapper 0 [000] 537.037184: sched_switch: prev_comm=swapper prev_pid=0...
sshd 1675 [000] 537.037309: sched_switch: prev_comm=sshd prev_pid=1675...
netstat 1692 [001] 537.038664: sched_switch: prev_comm=netstat prev_pid=1692...
2. trace, custom format
perf record -ga -e sched:sched_switch
perf script -f comm,pid,time,trace <--- omitting cpu and event name
swapper 0 537.037184: prev_comm=swapper prev_pid=0 prev_prio=120 ...
sshd 1675 537.037309: prev_comm=sshd prev_pid=1675 prev_prio=120 ...
netstat 1692 537.038664: prev_comm=netstat prev_pid=1692 prev_prio=120 ...

git://git.kernel.org/pub/scm/linux/kernel/git/acme/linux-2.6 into perf/core

Free the perf trace name space and rename the trace to 'script' which is a
better match for the scripting engine.
