Message Formatting

Telepipe supports three formatting modes:

Markdown Mode (--format markdown)

Uses Telegram's MarkdownV2 formatting with automatic escaping of special characters:

• Bold: *bold text*
• Italic: _italic text_
• Inline code: `inline code`
• Code blocks:

  ```language
  code block
  ```
  

Example:

echo "*Important*: Server status is \`ONLINE\`" | telepipe --format markdown

HTML Mode (--format html)

Uses HTML formatting tags:

• Bold: <b>bold text</b>
• Italic: <i>italic text</i>
• Inline code: <code>inline code</code>
• Code blocks: <pre>code block</pre>

Example:

echo "<b>Alert</b>: Database backup <code>COMPLETED</code>" | telepipe --format html

Plain Text Mode (--format none or default)

Sends messages without any formatting - useful when you want to send literal markdown/HTML characters.

Scheduled Message Delivery

Telepipe supports scheduling messages for future delivery in two ways:

Absolute Time Scheduling (--schedule)

Schedule a message for a specific date and time:

# Schedule a reminder for a specific time
echo "Meeting starts in 15 minutes" | telepipe --schedule "2025-05-28 14:45:00"
Schedule daily reports
echo "Daily backup completed successfully" | telepipe --schedule "2025-05-29 09:00:00"
Works with formatting
echo "Important: Server maintenance begins now" | telepipe --schedule "2025-05-28 22:00:00" --format markdown

Relative Time Delay (--delay)

Delay message delivery by a specified number of seconds:

# Send reminder in 1 hour (3600 seconds)
echo "Backup completed" | telepipe --delay 3600
Send alert in 30 minutes (1800 seconds)
echo "⚠️ Maintenance window starting soon" | telepipe --delay 1800
Quick 5-minute delay
echo "Process finished successfully" | telepipe --delay 300

Notes:

• Scheduled messages run as background processes
• The process ID is displayed for tracking (unless using --quiet)
• Scheduling cannot be combined with --interactive mode
• Time format for --schedule is: YYYY-MM-DD HH:MM:SS
• Scheduled time must be in the future

File Upload

Telepipe can upload files directly to Telegram while preserving their original filenames:

Basic File Upload

# Upload a file
telepipe --file backup.tar.gz
telepipe --file /path/to/document.pdf
telepipe --file ~/Downloads/movie.mp4
Upload with quiet mode (no URL output)
telepipe --file large-backup.zip --quiet

File Upload with Caption

You can add a caption to uploaded files by piping text to telepipe:

# Add caption from command line
echo "Database backup from $(date)" | telepipe --file backup.sql
Add caption from another command
hostname | telepipe --file system-report.txt
Multi-line caption
echo -e "Weekly Report\nGenerated: $(date)\nSize: $(du -h report.pdf)" | telepipe --file report.pdf

Practical Examples

# Backup with timestamp caption
echo "Backup completed at $(date)" | telepipe --file backup-$(date +%Y%m%d).tar.gz
Log file with context
echo "Error logs from server crash at $(date)" | telepipe --file /var/log/error.log
Automated script backup
tar -czf backup.tar.gz /important/data && echo "Backup created: $(du -h backup.tar.gz)" | telepipe --file backup.tar.gz

Notes:

• Maximum file size: 50MB (Telegram Bot API limit)
• Supports all file types
• Original filename is preserved
• Cannot be combined with --interactive, --schedule, or --delay options
• Caption text supports the same formatting as regular messages when used with --format

Video Streaming

Telepipe supports optimized video uploads with streaming playback directly in Telegram:

Basic Video Upload

# Upload video with streaming support
telepipe --video movie.mp4
telepipe --video /path/to/video.avi
telepipe --video recording.mov
Upload with quiet mode
telepipe --video large-video.mp4 --quiet

Video Upload with Caption

# Add caption to video
echo "Movie night! 🎬" | telepipe --video film.mp4
echo "Security footage from $(date)" | telepipe --video camera-feed.mp4
Formatted caption
echo "Important: Training video" | telepipe --video training.mp4 --format markdown

Advanced Features

• Automatic metadata detection: If ffprobe (from FFmpeg) is installed, telepipe automatically detects:

  • Video duration
  • Resolution (width/height)
  • These enhance the streaming experience in Telegram

• Streaming optimization: Videos are sent using Telegram's sendVideo API with supports_streaming=true, enabling:

  • Inline playback in chat
  • Better video player interface
  • Thumbnail generation
  • Progress bar during playback

Install FFmpeg for Better Support

# macOS
brew install ffmpeg
Ubuntu/Debian
sudo apt install ffmpeg
CentOS/RHEL
sudo yum install ffmpeg

Practical Examples

# Screen recording with timestamp
echo "Screen recording from $(date)" | telepipe --video screen-capture.mp4
Security camera upload
echo "Motion detected at front door" | telepipe --video security-$(date +%H%M).mp4
Meeting recording
echo "📹 Team meeting recording - $(date '+%Y-%m-%d')" | telepipe --video meeting.mp4 --format markdown

Video vs File Upload:

• Use --video for: MP4, AVI, MOV, MKV, WebM video files
• Use --file for: Documents, archives, images, audio, or when you want document-style upload

Notes:

• Maximum video size: 50MB (Telegram Bot API limit)
• Supports common video formats (MP4, AVI, MOV, MKV, WebM, etc.)
• Automatic streaming optimization

# /format markdown
# /format html
# /status
