    SYNOPSIS
    --------
    [verse]
    -'perf trace' [-i <file> | --input=file] symbol_name
    +'perf trace' {record <script> | report <script> [args] }

    DESCRIPTION
    -----------
    This command reads the input file and displays the trace recorded.

    +There are several variants of perf trace:
    +
    + 'perf trace' to see a detailed trace of the workload that was
    + recorded.
    +
    + 'perf trace record <script>' to record the events required for 'perf
    + trace report'. <script> is the name displayed in the output of
    + 'perf trace --list' i.e. the actual script name minus any language
    + extension.
    +
    + 'perf trace report <script>' to run and display the results of
    + <script>. <script> is the name displayed in the output of 'perf
    + trace --list' i.e. the actual script name minus any language
    + extension. The perf.data output from a previous run of 'perf trace
    + record <script>' is used and should be present for this command to
    + succeed.
    +
    OPTIONS
    -------
    -D::
    --dump-raw-trace=::
    Display verbose dump of the trace data.

    +--list=::
    + Display a list of available trace scripts.
    +
    -s::
    --script=::
    Process trace data with the given script ([lang]:script[.ext]).
