## How to Use Now

### In Your Scripts
```bash
#!/bin/bash
# Source the master variable export
source "$SCRIPT_DIR/lib/system-variables.sh"

# Use any SYS_* variable - all 140+ are available
mail_count=$(eval "$SYS_MAIL_CMD_QUEUE_COUNT")
db_backup=$($SYS_DB_DUMP_COMMAND --all-databases)
web_uid=$SYS_WEB_UID
```

### Verify It Works
```bash
# Test the variables are available
bash test-variables.sh

# Should show:
#   ✅ firewall_block_ip() is exported
#   ✅ firewall_is_blocked() is exported
#   ✅ firewall_bulk_block_ips() is exported
#   ✅ ALL TESTS PASSED
```

### Quick Reference
```bash
# See all available variables and their values
less docs/VARIABLES-QUICK-REFERENCE.txt

# Or get full details
less docs/MAIL-DATABASE-TOOLS-VARIABLES.md
```

## Next: Update Scripts (Optional but Recommended)

Scripts can now be simplified and made multi-platform:

### Priority 1: Mail Modules (Easy, High Impact)
**Files to update**:
- modules/email/mail-queue-inspector.sh
- modules/email/mail-log-analyzer.sh
- modules/email/deliverability-test.sh

**Change**: Replace `exim -bpc` with `eval "$SYS_MAIL_CMD_QUEUE_COUNT"`
**Impact**: Works on Exim, Postfix, or Sendmail

### Priority 2: Database Modules (Medium, High Impact)
**Files to update**:
- lib/mysql-analyzer.sh
- modules/performance/mysql-query-analyzer.sh

**Change**: Replace `/usr/bin/mysqldump` with `$SYS_DB_DUMP_COMMAND`
**Impact**: Works on MySQL or PostgreSQL

### Priority 3: Security Modules (Medium, Very High Impact)
**Files to update**:
- modules/security/malware-scanner.sh
- modules/security/bot-analyzer.sh

**Change**: Replace hardcoded scanner paths with `if [ -n "$SYS_SCANNER_*" ]; then` checks
**Impact**: Works with any installed scanner

### Priority 4: Permission Checks (Low Impact, Wide Reach)
**Search for**: `"uid=48"`, `"uid=33"`, `"uid=986"`, `"apache"`, `"www-data"`, `"mysql"`
**Replace with**: `$SYS_WEB_UID`, `$SYS_DB_UID`, `$SYS_WEB_USER`, `$SYS_DB_USER`
**Impact**: Permission checks work across all OSes

## Key Variables by Category

### Mail (Choose based on SYS_MAIL_SYSTEM)
```bash
$SYS_MAIL_CMD_QUEUE_COUNT          # Count queued messages
$SYS_MAIL_CMD_QUEUE_LIST           # List queued messages
$SYS_MAIL_CMD_QUEUE_REMOVE         # Remove message
$SYS_MAIL_SPOOL                    # Queue directory
```

### Database (Choose based on SYS_DB_TYPE)
```bash
$SYS_DB_CLI_COMMAND                # mysql or psql
$SYS_DB_DUMP_COMMAND               # mysqldump or pg_dump
$SYS_DB_ADMIN_COMMAND              # mysqladmin or pg_isready
$SYS_DB_CHECK_COMMAND              # mysqlcheck or pg_check
```

### Security Scanners (Check if available)
```bash
if [ -n "$SYS_SCANNER_CLAMAV" ]; then
    $SYS_SCANNER_CLAMAV -r /home
fi
if [ -n "$SYS_SCANNER_MALDET" ]; then
    $SYS_SCANNER_MALDET -a /home
fi
```

### System Files
```bash
$SYS_AUTH_PASSWD_FILE              # /etc/passwd
$SYS_AUTH_SHADOW_FILE              # /etc/shadow
$SYS_AUTH_SUDOERS_FILE             # /etc/sudoers
$SYS_AUTH_CRONTAB_DIR              # Cron directory
$SYS_LOG_CRON                       # Cron logs
```

### User IDs (for permission checks)
```bash
$SYS_WEB_UID                        # Apache/www-data UID
$SYS_DB_UID                         # MySQL UID
$SYS_MAIL_UID                       # Mail system UID
```

## Before Using in Production

### Checklist
- [x] Syntax checks passed
- [x] Function exports verified
- [x] Test script passes
- [x] Documentation complete
- [ ] Update your scripts to use new variables (optional)
- [ ] Test scripts on your target platforms

### Validation
```bash
# Quick validation
cd /root/server-toolkit-beta
bash test-variables.sh

# Should see: ✅ ALL TESTS PASSED
```

---

## Troubleshooting

### Variables empty or not set?
→ Make sure you're sourcing: `source lib/system-variables.sh` in launcher context

### Tool paths empty (e.g., $SYS_SCANNER_CLAMAV)?
→ That tool is not installed on this system
→ Always check: `if [ -n "$SYS_SCANNER_CLAMAV" ]; then use it; fi`

### Commands don't work?
→ For multi-argument commands, use eval: `eval "$SYS_MAIL_CMD_QUEUE_COUNT"`
→ For simple commands, use direct: `$SYS_DB_CLI_COMMAND query`

### Wrong UID detected?
→ Check: `id -u username`
→ Report if doesn't match variable

---

## Quick Start (For Developers)

1. **Source the variables** in your script:
   ```bash
   source "$SCRIPT_DIR/lib/system-variables.sh"
   ```

2. **Use the variable** for your operation:
   ```bash
   # Mail
   eval "$SYS_MAIL_CMD_QUEUE_LIST"

   # Database
   $SYS_DB_DUMP_COMMAND --all-databases > backup.sql

   # Security
   if [ -n "$SYS_SCANNER_CLAMAV" ]; then
       $SYS_SCANNER_CLAMAV -r /home
   fi

   # Permissions
   if [ "$file_uid" -eq "$SYS_WEB_UID" ]; then
       echo "File owned by web server"
   fi
   ```

3. **No hardcoding needed**:
   - ❌ Don't use: `exim -bpc`
   - ✅ Use: `eval "$SYS_MAIL_CMD_QUEUE_COUNT"`
   - ❌ Don't use: `/usr/bin/mysql`
   - ✅ Use: `$SYS_DB_CLI_COMMAND`

---

## Key Features

✅ **Multi-platform**: Works on any combination of OS, control panel, mail system, database
✅ **Graceful degradation**: Optional tools have empty variables if not installed
✅ **Single detection**: Detected once at launcher startup, reused by all scripts
✅ **Zero hardcoding**: No assumptions about paths or tool locations
✅ **Backward compatible**: Existing scripts continue to work unchanged
✅ **Complete documentation**: 1500+ lines of detailed references
