How to Use Now

In Your Scripts

#!/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

# 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

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)

$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)

$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)

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

$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)

$SYS_WEB_UID                        # Apache/www-data UID
$SYS_DB_UID                         # MySQL UID
$SYS_MAIL_UID                       # Mail system UID

Before Using in Production

Checklist

• Syntax checks passed
• Function exports verified
• Test script passes
• Documentation complete
• Update your scripts to use new variables (optional)
• Test scripts on your target platforms

Validation

# 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:

   source "$SCRIPT_DIR/lib/system-variables.sh"
   

2. Use the variable for your operation:

   # 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
