mf — Make File

mf is a cross-platform CLI tool for creating files from the command line — like touch but with clipboard, encoding detection, content type detection, batch creation, and interactive conflict resolution.

Quick Install

cargo install mf

Or build from source:

git clone https://github.com/user/mf.git
cd mf
cargo build --release

Quick Usage

# Create an empty file
mf config.ini

# Write clipboard content to file
mf output.txt

# Save clipboard image to file
mf screenshot.png -c

# Read file content into clipboard
mf -i source.txt

# Preview clipboard content
mf -p

# Create multiple files at once
mf a.txt b.txt c.txt

# Create with specific encoding
mf script.bat --encoding gbk

# Force overwrite (creates .bak backup)
mf report.md -f

# Don't overwrite existing files
mf notes.md --no-clobber

# Rename new file on conflict
mf data.csv --conflict rename

# Set max size limit (MB)
mf large.txt --max-size 10

# Set language
mf --lang zh-CN output.txt

# Quiet mode (no output)
mf -q output.txt

# Verbose mode
mf -v output.txt

Help Flags

mf --help-config       # Config file reference

Features

• Create empty files — mf <path> works like touch
• Clipboard write — writes clipboard text/image to file (default action)
• Clipboard image save — -c saves clipboard images as PNG/JPEG/BMP/GIF/ICO/WEBP
• Clipboard preview — -p previews clipboard content with type detection
• File to clipboard — -i/--from-file reads file content into clipboard
• Batch creation — create any number of files in one command
• Encoding control — automatic per-extension defaults, manual --encoding, auto-detection via chardetng
• Encoding conversion — supports utf-8, utf-8-bom, utf-16le, gbk with full round-trip conversion
• Content type detection — auto-detects 20+ types (JSON, XML, HTML, Python, Rust, etc.), warns on extension mismatch
• Interactive confirmation — prompts to adjust extension when type doesn't match
• Conflict resolution — --conflict with skip/rename/append/overwrite, interactive prompt by default
• Force overwrite — -f/--force overwrites existing file with .bak backup
• No-clobber — --no-clobber skips existing files silently
• Append mode — --append appends clipboard content to existing file
• Max size limit — --max-size <MB> rejects content exceeding the limit
• Quiet mode — -q/--quiet suppresses all output
• Verbose mode — -v/--verbose shows encoding and action details
• Signal handling — graceful exit on Ctrl+C with cleanup
• Atomic writes — writes to temp file first, then renames; no data loss on failure
• Cross-platform — Windows, Linux, macOS

Internationalization

mf auto-detects your system language and supports 6 locales:

Code	Language
en	English (default fallback)
zh-CN	Simplified Chinese
zh-TW	Traditional Chinese
de	German
ja	Japanese
ko	Korean

Override with --lang:

mf --lang de output.txt
mf --lang ja --help-encoding
