Tip checklist (authorized only)
- Confirm you may read memory stats on the host (lab VM / your sample / courseware).
- Prefer
free -h/free -mshort human views over unrelated dumps. - Record
-h/-m/-sflags you actually used. - Quote total/used/free/available Evidence; redact hostnames.
- If you need disk free framing, cross-check free-disk-tips.
- Optional: vmstat sample → vmstat-tips; mem framing → vmstat-mem-tips.
- Optional: disk cousins → df-human-tips · du-summarize-tips.
- Redact sensitive labels before sharing; never dump process memory for secrets.
Allowed framing
- Classroom labs reading RAM/swap on a syllabus VM.
- Binding
-h/-msettings as Evidence. - Documenting "free not installed / permission denied" as valid lab outcomes.
- Comparing free ↔ vmstat under one binder.
Scope we will not cover

Beginner path (authorized only)

FAQ
What is a "free mem tip" page in BinBench framing?
A checklist for reading authorized RAM/swap stats on hosts you own — not a cookbook for profiling hosts you do not control.
How does this relate to free-disk-tips and vmstat-mem-tips?
free-disk-tips covers disk free framing; vmstat-mem-tips covers vmstat memory. This page zooms on free memory Evidence — it does not overwrite those pages.
Can I free-profile other users\' production hosts I do not administer?
No. Authorization first. BinBench will not publish unauthorized-access recipes.
Does this teach exploit / OOM-abuse PoCs?
No. Mentions of exploit appear only as refusals. Authorized memory literacy only.
Does this teach credential theft via mem dumps?
No. Redact hostnames before sharing; never dump process memory for secrets.
