TRACE-CMD-CLEAR(1)          libtracefs Manual         TRACE-CMD-CLEAR(1)

NAME 

       trace-cmd-clear - clear the Ftrace buffer.

SYNOPSIS 

       trace-cmd clear [OPTIONS]

DESCRIPTION 

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

OPTIONS 

       -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.
