CLI behavior, verified. Kernel version noted.
Every article here includes full terminal output, version callouts for 6.1 and 5.15, and the flag interactions nobody else bothered to run.
Articles with actual output
inotifywait: what changes between kernel versions
The --monitor flag behaves differently when chained with --format on 5.15 versus 6.1. Both outputs are included; the divergence point is annotated.
perf stat: chaining -e with --cpu
The interaction between -e cycles and --cpu is undocumented in the man page. Tested on bare metal with pinned affinity; the trap and fix are both shown.
Real output, both kernels
$ journalctl --since '2024-01-01 00:00:00' --until '2024-01-01 01:00:00' -u sshd --output=json-pretty
Where 5.15 and 6.1 diverge, the article calls it out explicitly. No paraphrasing — the raw command-response pairs are in every entry.
On 5.15: --output=json-pretty silently falls back to short when --since and --until are both active. On 6.1 the flag is respected. The man page says nothing about this.
