 +'perf script' [<options>] report <script> [script-args]

 +DESCRIPTION
 +-----------
 +This command reads the input file and displays the trace recorded.
 +
 +There are several variants of perf script:
 +
 +  'perf script' to see a detailed trace of the workload that was
 +  recorded.
 +
 +  You can also run a set of pre-canned scripts that aggregate and
 +  summarize the raw trace data in various ways (the list of scripts is
 +  available via 'perf script -l').  The following variants allow you to
 +  record and run those scripts:
 +
 +  'perf script record <script> <command>' to record the events required
 +  for 'perf script report'.  <script> is the name displayed in the
 +  output of 'perf script --list' i.e. the actual script name minus any
 +  language extension.  If <command> is not specified, the events are
 +  recorded using the -a (system-wide) 'perf record' option.
 +
 +  'perf script report <script> [args]' 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 script
 +  record <script>' is used and should be present for this command to
 +  succeed.  [args] refers to the (mainly optional) args expected by
 +  the script.
 +
 +  'perf script <script> <required-script-args> <command>' to both
 +  record the events required for <script> and to run the <script>
 +  using 'live-mode' i.e. without writing anything to disk.  <script>
 +  is the name displayed in the output of 'perf script --list' i.e. the
 +  actual script name minus any language extension.  If <command> is
 +  not specified, the events are recorded using the -a (system-wide)
 +  'perf record' option.  If <script> has any required args, they
 +  should be specified before <command>.  This mode doesn't allow for
 +  optional script args to be specified; if optional script args are
 +  desired, they can be specified using separate 'perf script record'
 +  and 'perf script report' commands, with the stdout of the record step
 +  piped to the stdin of the report script, using the '-o -' and '-i -'
 +  options of the corresponding commands.
 +
 +  'perf script <top-script>' to both record the events required for
 +  <top-script> and to run the <top-script> using 'live-mode'
 +  i.e. without writing anything to disk.  <top-script> is the name
 +  displayed in the output of 'perf script --list' i.e. the actual
 +  script name minus any language extension; a <top-script> is defined
 +  as any script name ending with the string 'top'.
 +
 +  [<record-options>] can be passed to the record steps of 'perf script
 +  record' and 'live-mode' variants; this isn't possible however for
 +  <top-script> 'live-mode' or 'perf script report' variants.
 +
 +  See the 'SEE ALSO' section for links to language-specific
 +  information on how to write and run your own trace scripts.
 +
 +OPTIONS
 +-------
 +<command>...::
 +	Any command you can specify in a shell.
 +
 +-D::
 +--dump-raw-script=::
 +        Display verbose dump of the trace data.
 +
 +-L::
 +--Latency=::
 +        Show latency attributes (irqs/preemption disabled, etc).
 +
 +-l::
 +--list=::
 +        Display a list of available trace scripts.
 +
 +-s ['lang']::
 +--script=::
 +        Process trace data with the given script ([lang]:script[.ext]).
 +	If the string 'lang' is specified in place of a script name, a
 +        list of supported languages will be displayed instead.
 +
 +-g::
 +--gen-script=::
 +        Generate perf-script.[ext] starter script for given language,
 +        using current perf.data.
 +
 +-a::
 +        Force system-wide collection.  Scripts run without a <command>
 +        normally use -a by default, while scripts run with a <command>
 +        normally don't - this option allows the latter to be run in
 +        system-wide mode.
 +
++-i::
++--input=::
++        Input file name.
++
++-d::
++--debug-mode::
++        Do various checks like samples ordering and lost events.
