# Filesystem search

terminal-tools provides two structured search tools: `terminal_rg` (ripgrep for content) and `terminal_find` (find for predicates). Everything else (tree, stat, du) is just `terminal_exec`.

## When to use what

| Task | Tool |
|---|---|
| Find code/text matching a pattern in your **project** | `files-tools.search_files` (project-aware, ranks by relevance) |
| Find code/text matching a pattern in `/var/log`, `/etc`, archives, system dirs | `terminal_rg` |
| Find files matching name/glob/predicate | `terminal_find` |
| List a directory | `terminal_exec("ls -la /path")` |
| Tree view | `terminal_exec("tree -L 2 /path")` |
| Single-path stat | `terminal_exec("stat /path")` |
| Disk usage | `terminal_exec("du -sh /path")` or `terminal_exec("du -h --max-depth=2 /")` |
| Count matches across files | `terminal_rg(pattern, count=True via extra_args=["-c"])` |

## `terminal_rg` — content search

ripgrep is fast, gitignore-aware, and has a deep flag surface. The structured wrapper exposes the most useful flags directly; `extra_args` covers the rest.

### Common patterns

```
# All Python files containing "TODO"
terminal_rg(pattern="TODO", path=".", type_filter="py")

# Case-insensitive, with context
terminal_rg(pattern="error", path="/var/log", ignore_case=True, context=2)

# Search hidden files (rg ignores them by default)
terminal_rg(pattern="api_key", path="~", hidden=True)

# Don't respect .gitignore (find files git would ignore)
terminal_rg(pattern="generated", path=".", no_ignore=True)

# Multi-line pattern (e.g., function definitions spanning lines)
terminal_rg(pattern=r"def\s+\w+\(.*\n.*\n", path="src", extra_args=["--multiline"])

# Specific filename glob
terminal_rg(pattern="version", path=".", glob="*.toml")
```

### rg flag idioms

| Flag | Effect |
|---|---|
| `-tpy` (`type_filter="py"`) | Only Python files |
| `-uu` | Don't respect any ignores (incl. `.git/`) |
| `--multiline` (`extra_args`) | Allow regex spanning lines |
| `--max-count` (`max_count`) | Stop after N matches per file |
| `--max-depth` (`max_depth`) | Limit recursion |
| `-w` (`extra_args`) | Whole word match |
| `-F` (`extra_args`) | Fixed string (no regex) |

See `references/ripgrep_cheatsheet.md` for the long form.

## `terminal_find` — predicate search

`find` excels at "files matching N criteria". The wrapper surfaces the most common predicates; combine via the structured arguments.

```
# All .log files modified in the last 7 days, larger than 1MB
terminal_find(path="/var/log", iname="*.log", mtime_days=7, size_kb_min=1024)

# All directories named ".git" (find Git repos under a tree)
terminal_find(path="~/projects", name=".git", type_filter="d")

# Only the top three levels
terminal_find(path="/etc", max_depth=3, type_filter="f")

# Symlinks
terminal_find(path=".", type_filter="l")
```

See `references/find_predicates.md` for combinations not directly exposed.

## Output truncation

Both tools return `truncated: true` when their output exceeded the inline cap. For `terminal_rg`, this means matches were dropped (refine the pattern or narrow the path); for `terminal_find`, results past `max_results` (default 1000) are dropped. Tighten predicates rather than raising the cap.

## Anti-patterns

- **Don't `terminal_rg` your project tree** — `files-tools.search_files` is project-aware and ranks results.
- **Don't reach for `terminal_find` to list one directory** — `terminal_exec("ls -la /path")` is shorter.
- **Don't use `terminal_exec("grep ...")`** when `terminal_rg` exists — rg is faster, gitignore-aware, and returns structured matches.
- **Don't use `terminal_exec("find ...")`** to invent your own predicate combinations — use `terminal_find` and report missing capabilities.
