# Virtual Filesystem

You work in a terminal over a virtual filesystem. Read files with shell
commands.

Command output comes back whole, however long. Some files here are large,
so point `grep -r`, `rg`, `find` and `cat` at the directory or file you
need rather than at a whole mount.

| path | what it is |
|---|---|
| `/mongodb` | Your MongoDB databases, read-only; change them with the `mongodb` CLI. |
| `/tmp` | Scratch space, in memory. |

## `/mongodb`

```
/mongodb/
  <database>/
    database.json
    collections/
      <collection>/
        schema.json
        documents.jsonl
    views/
      <view>/
        schema.json
        documents.jsonl
```

- `database.json`: `{database: str, collections: list[{name: str}],
  views: list[{name: str}]}`
- `schema.json`: `{database: str, name: str, kind: str, validator: dict |
  null, fields: list[{path: str, presence: number, types: dict}],
  primary_key: str, indexes: list[{name: str, keys: dict, type: str}],
  sampled: int}`, read from a sample of `sampled` documents
- `documents.jsonl`: one document per line, in MongoDB Extended JSON: a date
  reads as `{"$date": "..."}`

/mongodb/
  <database>/
    database.json
    collections/
      <collection>/
        schema.json
        documents.jsonl
    views/
      <view>/
        schema.json
        documents.jsonl

# Available commands

Python (`python` or `python3`), Perl, JavaScript/Node.js, and TypeScript
runtimes are unavailable. Use the shell commands and task CLIs documented
below; do not probe for or attempt to install other runtimes.

Standard Unix commands, among them:

    cat  head  tail  ls  find  grep  wc  sort  uniq  cut  tr  sed  awk
    diff  tee  xargs  jq

with pipes, `>` redirection and `$(...)` substitution.

Do not probe the machine with `which`, `type`, `--version`, `env`, `ps`,
`echo $PATH`, `ls /usr/bin` or `cat /usr/bin/<command>`: they tell you
nothing about the task.

A filename with a space in it needs quoting, as it would in any shell.

You can also use `gh` for GitHub.
