TRACE-CMD-START(1) libtracefs Manual TRACE-CMD-START(1)
NAME
trace-cmd-start - start the Ftrace Linux kernel tracer without
recording
SYNOPSIS
trace-cmd start [OPTIONS]
DESCRIPTION
The trace-cmd(1) start enables all the Ftrace tracing the same
way trace-cmd-record(1) does. The difference is that it does not
run threads to create a trace.dat file. This is useful just to
enable Ftrace and you are only interested in the trace after some
event has occurred and the trace is stopped. Then the trace can
be read straight from the Ftrace pseudo file system or can be
extracted with trace-cmd-extract(1).
OPTIONS
The options are the same as trace-cmd-record(1), except that it
does not take options specific to recording (-s, -o, -N, and -t).
--fork
This option is only available for trace-cmd start. It tells
trace-cmd to not wait for the process to finish before
returning. With this option, trace-cmd start will return
right after it forks the process on the command line. This
option only has an effect if trace-cmd start also executes a
command.
