+> `--workspace ` β€” workspace directory for three-step workflow (NEW).
+> `--source ` β€” one or more directories to search. (`--root` is still accepted as an alias.)
> `--start "YYYY-MM-DD HH:MM:SS"` β€” window start (local time).
-> `--minutes <1–60>` β€” duration; must stay within a single calendar day. Or use `--end` with same-day end time.
-> `--out ` β€” output file (not required if you use --dry-run).
+> `--minutes <1–1440>` β€” duration; must stay within a single calendar day. Or use `--end` with same-day end time.
### Optional ❓ + +**Workflow Control:** +> `--step {1,2,3,all}` β€” which step to run (default: all).
+> `--resume` β€” resume from existing workflow state.
+> `--status` β€” show workflow status and exit.
+ +**Pattern Filtering (Step 1): +> `--include-pattern [PATTERNS...]` β€” include files matching patterns (default: *.pcap, *.pcapng).
+> `--exclude-pattern [PATTERNS...]` β€” optional excludes (none by default).
+> `--selection-mode {manifest|symlink}` β€” how to materialize selections. Default: manifest. Use `symlink` to browse selections in a workspace folder.
+ +**Processing Options:** > `--end ` β€” end time instead of `--minutes` (must be same day as `--start`).
-> `--tmpdir ` β€” where to write temporary/intermediate files. **Highly recommended** on a large volume (e.g., the NAS).
> `--batch-size ` β€” files per merge batch (default: 500).
> `--slop-min ` β€” mtime prefilter slack minutes (default: 120).
> `--precise-filter` β€” use capinfos first/last packet times to keep only overlapping files.
> `--workers ` β€” concurrency for precise filter (default: auto β‰ˆ 2Γ—CPU, gently capped).
> `--display-filter ""` β€” post-trim filter via tshark (e.g., "dns", "tcp.port==443").
> `--out-format {pcap|pcapng}` β€” final capture format (default: pcapng).
-> `--gzip` β€” gzip-compress the final output (writes .gz).
+> `--out ` β€” explicit output path for Step 2 (otherwise written under workspace).
+> `--tmpdir ` β€” directory for temporary files during Step 2 (overrides system/workspace tmp).
+ +**Cleaning Options (Step 3):** +> `--snaplen ` β€” truncate packets to N bytes.
+> `--convert-to-pcap` β€” force conversion to pcap format.
+> `--gzip` β€” gzip-compress the final output.
+ +**Other:** > `--dry-run` β€” selection only; no merge/trim/write.
-> `--list-out ` β€” with `--dry-run`, write survivor list to file.
-> `--report ` β€” write a CSV report for survivors with path,size,mtime,first,last (uses cache/capinfos).
-> `--summary` β€” with `--dry-run`, print min/max packet times across survivors (UTC). -> `--verbose` β€” print debug logs and show external tool output. +> `--verbose` β€” print debug logs and show external tool output.
