6 perf-script - Read perf.data (created by perf record) and display trace output

18 -----------
26 You can also run a set of pre-canned scripts that aggregate and
28 available via 'perf script -l'). The following variants allow you to
33 output of 'perf script --list' i.e. the actual script name minus any
35 recorded using the -a (system-wide) 'perf record' option.
37 'perf script report <script> [args]' to run and display the results
39 script --list' i.e. the actual script name minus any language
45 'perf script <script> <required-script-args> <command>' to both
47 using 'live-mode' i.e. without writing anything to disk. <script>
48 is the name displayed in the output of 'perf script --list' i.e. the
50 not specified, the events are recorded using the -a (system-wide)
56 piped to the stdin of the report script, using the '-o -' and '-i -'
59 'perf script <top-script>' to both record the events required for
60 <top-script> and to run the <top-script> using 'live-mode'
61 i.e. without writing anything to disk. <top-script> is the name
62 displayed in the output of 'perf script --list' i.e. the actual
63 script name minus any language extension; a <top-script> is defined
66 [<record-options>] can be passed to the record steps of 'perf script
67 record' and 'live-mode' variants; this isn't possible however for
68 <top-script> 'live-mode' or 'perf script report' variants.

79 --dump-raw-trace=::
80 Display verbose dump of the trace data.
82 -L::

88 Display a list of available trace scripts.

97 --gen-script=::
98 Generate perf-script.[ext] starter script for given language,
101 -a::
102 Force system-wide collection. Scripts run without a <command>
103 normally use -a by default, while scripts run with a <command>
104 normally don't - this option allows the latter to be run in
105 system-wide mode.

129 perf script -F trace:<fields> -F sw:<fields> -F hw:<fields>
137 -F -cpu,+insn
145 -F trace: -F comm,tid,time,ip,sym
147 The first -F suppresses trace events (field list is ""), but then the
155 -F comm,tid,time,ip,sym -F trace:
157 The first -F sets the fields for all events and the second -F
166 $ perf script -F comm,tid,trace
173 perf script -v -F sw:comm,tid,trace
176 At this point usage is displayed, and perf-script exits.
186 "tr end" for "bE". However the "x" flag will be display separately in those
190 Instruction Trace decoding. For calls and returns, it will display the
