AirCheck

Flight deal monitoring script that watches SecretFlying.com for deals to specific airports and sends email notifications.

Features

• Monitors flight deals for LAX (Los Angeles) and BWI (Baltimore) airports
• Secure email configuration via environment variable
• Duplicate detection to avoid spam
• Error handling and logging
• Automatic cleanup of temporary files

Security

The script uses an environment variable for the email address to avoid hardcoding sensitive information. The email address is stored as a global environment variable on the system.

Setup

1. Make the script executable:

   chmod +x aircheck.sh

2. Email address is configured globally:

   • The email address must be stored in ~/.bashrc and ~/.profile
   • To set it, edit the AIRCHECK_EMAIL variable in ~/.bashrc:

     export AIRCHECK_EMAIL="your-email@example.com"

   • Then reload your shell configuration:

     source ~/.bashrc

   The script will automatically use this global variable. No need to export it each time you run the script. Note: The email address is not stored in any script files for security.

3. Ensure you have a mail client configured on your system:

   • mail command (usually via mailutils or mailx)
   • Or sendmail command

Usage

Run the script:

./aircheck.sh

For automated monitoring, add to crontab:

# Run every 6 hours
0 */6 * * * cd /path/to/AirCheck && ./aircheck.sh >> aircheck.log 2>&1

Files

• aircheck.sh - Main monitoring script
• exclude.txt - Tracks already-notified deals (auto-created)
• Final.txt - Latest parsed flight deal data

Airport Codes Monitored

• LAX - Los Angeles International Airport
• BWI - Baltimore/Washington International Airport

The script searches for these airport codes and common city name variations in deal titles.
