# mvx / cpx

Enhanced `mv` and `cp` commands with directory merging and progress bars.

## Installation

```bash
cargo install --path .
```

This installs both `mvx` (move) and `cpx` (copy) binaries.

## Usage

```
mvx [OPTIONS] <SOURCES>... <DEST>
cpx [OPTIONS] <SOURCES>... <DEST>
```

### Options

| Option | Description |
|--------|-------------|
| `-f, --force` | Overwrite existing files |
| `-n, --dry-run` | Show what would be done without actually doing it |
| `-q, --quiet` | Suppress progress bars and info messages |
| `-v, --verbose` | Show detailed output |
| `-h, --help` | Print help |
| `-V, --version` | Print version |

## Behavior Matrix

Key differences from `mv`/`cp`: directories are **merged** (not nested), destination directories are **created automatically**, and existing files are **never overwritten** unless `-f` is specified.

### Single source

| Source | Dest is file | Dest is directory | Dest doesn't exist | Dest doesn't exist (trailing `/`) |
|--------|-------------|-------------------|--------------------|------------------------------------|
| File | Overwrites (`-f`) | Moves/copies into dir | Creates file | Creates dir, moves/copies into it |
| Dir | Error | Merges contents | Creates dir, merges | Creates dir, merges |

### Multiple sources

All sources must be the same kind (all files or all directories).

| Sources | Dest is file | Dest is directory | Dest doesn't exist | Dest doesn't exist (trailing `/`) |
|---------|-------------|-------------------|--------------------|-----------------------------------|
| Files | Error | Moves/copies each into dir | Error | Creates dir, moves/copies each into dir |
| Dirs | Error | Merges each into dir | Creates dir, merges each | Creates dir, merges each |
| Mixed | Error | Error | Error | Error |

## Features

### Progress Bars

Cross-device operations display progress bars with transfer speed and ETA:

```
   1.2 GiB [========>-------------------------------]  312 MiB (  45.2 MiB/s, ETA: 00:00:21 ) file.iso -> /mnt/backup/file.iso
```

Use `-q` to suppress progress output.

### Fast Path Optimization

Same-device moves use `rename` (instant). Same-filesystem copies use `reflink` (copy-on-write clone on APFS/Btrfs). The buffered copy fallback with progress bars only kicks in when these fast paths aren't available.

### Ctrl+C Handling

Press Ctrl+C once to finish the current file and stop. Press again to force exit immediately.

## Examples

```bash
# Move a single file
mvx file.txt /backup/

# Copy multiple files to a directory
cpx file1.txt file2.txt /dest/

# Merge directories (preserve existing, fail on conflicts)
mvx source_dir/ dest_dir/

# Merge directories (overwrite conflicts)
mvx -f source_dir/ dest_dir/

# Copy with progress bar suppressed
cpx -q large_file.iso /mnt/usb/
```
