Title:
`perf report` complains about missing tips.txt file
Status in linux package in Ubuntu:
Confirmed
Bug description:
The `perf` command-line tool expects a tips.txt file at
/usr/share/doc/perf-tip/tips.txt, from which it displays random tips
in `perf report` mode. If this file is not present (it is not on
Ubuntu 22.04 LTS), `perf report` complains, both in interactive and in
non-interactive mode, that:
> Cannot load tips.txt file, please install perf!
Reproduction:
$ mkdir tmpdir; cd tmpdir
$ perf record ls
$ perf report | cat
The expected behaviour is that this message is not shown (and a
(useful?) tip is shown instead).
This has led to bug reports (and fixes) on various other Linux
distributions: at least Fedora [1] and Arch [2].
