# CLI Scope Flags
|
|
|
|
Renamer shares a consistent set of scope flags across every command that inspects or mutates the
|
|
filesystem. Use these options at the root command level so they apply to all subcommands (`list`,
|
|
`replace`, `insert`, `remove`, etc.).
|
|
|
|
| Flag | Default | Description |
|
|
|------|---------|-------------|
|
|
| `--path` | `.` | Working directory root for traversal. |
|
|
| `-r`, `--recursive` | `false` | Traverse subdirectories depth-first. Symlinked directories are not followed. |
|
|
| `-d`, `--include-dirs` | `false` | Include directories in results. |
|
|
| `-e`, `--extensions` | *(none)* | Pipe-separated list of file extensions (e.g. `.jpg|.mov`). Tokens must start with a dot, are lowercased internally, and duplicates are ignored. |
|
|
| `--hidden` | `false` | Include dot-prefixed files and directories. By default they are excluded from listings and rename previews. |
|
|
| `--yes` | `false` | Apply changes without interactive confirmation (mutating commands only). |
|
|
| `--dry-run` | `false` | Force preview-only behavior even when `--yes` is supplied. |
|
|
| `--format` | `table` | Command-specific output formatting option. For `list`, use `table` or `plain`. |
|
|
|
|
## Insert Command Quick Reference
|
|
|
|
```bash
|
|
renamer insert <position> <text> [flags]
|
|
```
|
|
|
|
- Position tokens:
|
|
- `^` inserts at the beginning of the filename.
|
|
- `$` inserts immediately before the extension dot (or end if no extension).
|
|
- Positive integers (1-based) count forward from the start of the stem.
|
|
- Negative integers count backward from the end of the stem (e.g., `-1` inserts before the last rune).
|
|
- Text must be valid UTF-8 without path separators or control characters; Unicode characters are supported.
|
|
- Scope flags (`--path`, `-r`, `-d`, `--hidden`, `--extensions`) limit the candidate set before insertion.
|
|
- `--dry-run` previews the plan; rerun with `--yes` to apply the same operations.
|
|
|
|
### Usage Examples
|
|
|
|
- Preview adding a prefix: `renamer insert ^ "[2025] " --dry-run`
|
|
- Append before extension: `renamer insert $ _ARCHIVE --yes --path ./docs`
|
|
- Insert after third character in stem: `renamer insert 3 _tag --path ./images --dry-run`
|
|
- Combine with extension filter: `renamer insert ^ "v1_" --extensions .txt|.md`
|
|
|
|
## Remove Command Quick Reference
|
|
|
|
```bash
|
|
renamer remove <token1> [token2 ...] [flags]
|
|
```
|
|
|
|
- Removal tokens are evaluated in the order supplied. Each token deletes literal substrings from the
|
|
current filename before the next token runs; results are previewed before any filesystem changes.
|
|
- Duplicate tokens are deduplicated automatically and surfaced as warnings so users can adjust
|
|
scripts without surprises.
|
|
- Tokens that collapse a filename to an empty string are skipped with warnings during preview/apply
|
|
to protect against accidental deletion.
|
|
- All scope flags (`--path`, `-r`, `-d`, `--hidden`, `-e`) apply, making it easy to target directories,
|
|
recurse, and limit removals by extension.
|
|
- Use `--dry-run` for automation previews and combine with `--yes` to apply unattended; conflicting
|
|
combinations (`--dry-run --yes`) exit with an error to uphold preview-first safety.
|
|
|
|
### Usage Examples
|
|
|
|
- Preview sequential removals: `renamer remove " copy" " draft" --dry-run`
|
|
- Remove tokens recursively: `renamer remove foo foo- --recursive --path ./reports`
|
|
- Combine with extension filters: `renamer remove " Project" --extensions .txt|.md --dry-run`
|
|
|
|
## Extension Command Quick Reference
|
|
|
|
```bash
|
|
renamer extension <source-ext...> <target-ext> [flags]
|
|
```
|
|
|
|
- Provide one or more dot-prefixed source extensions followed by the target extension. Validation
|
|
fails if any token omits the leading dot or repeats the target exactly.
|
|
- Source extensions are normalized case-insensitively; duplicates and no-op tokens are surfaced as
|
|
warnings in the preview rather than silently ignored.
|
|
- Preview output lists every candidate with `changed`, `no change`, or `skipped` status so scripts
|
|
can detect conflicts before applying. Conflicting targets block apply and exit with a non-zero
|
|
code.
|
|
- Scope flags (`--path`, `-r`, `-d`, `--hidden`, `--extensions`) determine which files and
|
|
directories participate. Hidden assets remain excluded unless `--hidden` is supplied.
|
|
- `--dry-run` (default) prints the plan without touching the filesystem. Re-run with `--yes` to
|
|
apply; attempting to combine both flags exits with an error. When no files match, the command
|
|
exits `0` after printing “No candidates found.”
|
|
|
|
### Usage Examples
|
|
|
|
- Preview normalization: `renamer extension .jpeg .JPG .jpg --dry-run`
|
|
- Apply case-folded extension updates: `renamer extension .yaml .yml .yml --yes --path ./configs`
|
|
- Include hidden assets recursively: `renamer extension .TMP .tmp --recursive --hidden`
|
