4NAME
5----
6perf-buildid-list - List the buildids in a perf.data file

8SYNOPSIS
9--------
10[verse]
11'perf buildid-list <options>'
12
13DESCRIPTION
14-----------
15This command displays the buildids found in a perf.data file, so that other
16tools can be used to fetch packages with matching symbol tables for use by
17perf report.
18
19OPTIONS
20-------
21-i::
22--input=::
23 Input file name. (default: perf.data)
24-f::
25--force::
26 Don't do ownership validation.
27-v::
28--verbose::
29 Be more verbose, showing the name of the DSOs after the buildids.
