# Terminal/CLI Web Text

![webterminal](webterminal.png)

**v0.1**

A filtered extract of terminal and command-line content from two large web-text corpora.

## Sources

- **DCLM** (`Zyphra/dclm-dedup`)
- **FineWeb** (`Salesforce/fineweb_deduplicated`)

## How it was built

1. **Fast filter**: skip any document that doesn't contain obvious CLI indicators (`$`, `sudo`, `pip install`, `` ```bash ``, `root@`, etc.)
2. **Score**: remaining docs are scored (0-34) across five signals, each with a per-match point value and a cap:

| Filter | Description | Points | Cap |
|---|---|---|---|
| Prompt patterns | Shell prompts like `$ cmd`, `user@host:~$`, `>>>`, `root@`, `PS C:\` | 2 per match | 10 |
| CLI commands | Known commands: `sudo`, `apt-get`, `pip install`, `git clone`, `docker run`, `curl`, `ssh`, `gcc`, etc. (30+ patterns) | 1 per unique match | 8 |
| stdout patterns | Output indicators: "successfully installed", "cloning into", `drwx` (ls output), "packets transmitted", "traceback", version strings | 2 per match | 6 |
| Code blocks | Terminal-flavored code blocks: `` ```bash ``, `` ```shell ``, `<pre><code>`, terminal/console div classes | 2 per match | 6 |
| Indented blocks | 3+ consecutive lines indented 4+ spaces (code/output blocks) | 1 per match | 4 |

Documents scoring >=5 are kept.

3. **Dedup**: exact dedup across both datasets using xxhash64 on full text.

## Use case

Mostly for upsampling agentic-adjacent data during pretraining.
