NAME         top

       trace-cmd-clear - clear the Ftrace buffer.

SYNOPSIS         top

       trace-cmd clear [OPTIONS]

DESCRIPTION         top

       The trace-cmd(1) clear clears the content of the Ftrace ring
       buffer.

OPTIONS         top

       -B buffer-name
           If the kernel supports multiple buffers, this will clear only
           the given buffer. It does not affect any other buffers. This
           may be used multiple times to specify different buffers. The
           top level buffer will not be clearded if this option is given.

       -a
           Clear all existing buffers, including the top level one.
