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.
