NAME

6       trace-cmd-start - start the Ftrace Linux kernel tracer without
7       recording
8

SYNOPSIS

10       trace-cmd start [OPTIONS]
11

DESCRIPTION

13       The trace-cmd(1) start enables all the Ftrace tracing the same way
14       trace-cmd-record(1) does. The difference is that it does not run
15       threads to create a trace.dat file. This is useful just to enable
16       Ftrace and you are only interested in the trace after some event has
17       occurred and the trace is stopped. Then the trace can be read straight
18       from the Ftrace pseudo file system or can be extracted with
19       trace-cmd-extract(1).
20

OPTIONS

22       The options are the same as trace-cmd-record(1), except that it does
23       not take options specific to recording (-s, -o, -N, and -t).
24
25       --fork
26           This option is only available for trace-cmd start. It tells
27           trace-cmd to not wait for the process to finish before returning.
28           With this option, trace-cmd start will return right after it forks
29           the process on the command line. This option only has an effect if
30           trace-cmd start also executes a command.
