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.
