# System Maintenance
|
|
|
|
> ⚠️ This documentation is AI-generated and may contain errors.
|
|
|
|
Example system maintenance script demonstrating permission checks, environment variables, and log rotation.
|
|
|
|
## Script
|
|
|
|
See the full script in `/examples/system_maintenance.rsh` in the repository.
|
|
|
|
```rush
|
|
#!/usr/bin/env rush
|
|
|
|
HOSTNAME = "prod-server-01"
|
|
MAX_DISK_USAGE = "85"
|
|
LOG_DIR = "/var/log"
|
|
BACKUP_DIR = "$HOME/backups"
|
|
|
|
echo "System Maintenance Script"
|
|
echo "Running on: $HOSTNAME"
|
|
echo "User: $USER"
|
|
|
|
# Permission-aware execution
|
|
if $IS_ROOT {
|
|
echo "Running with root privileges"
|
|
|
|
for check in disk memory services {
|
|
echo "Checking $check status..."
|
|
if $check {
|
|
echo " ✓ $check is healthy"
|
|
}
|
|
}
|
|
} else {
|
|
echo "Running as $USER (limited permissions)"
|
|
echo "Some checks may be skipped"
|
|
}
|
|
|
|
# Log rotation planning
|
|
echo "Preparing log rotation in $LOG_DIR"
|
|
|
|
for days in 1 7 30 {
|
|
LOG_ARCHIVE = "$BACKUP_DIR/logs-$days-days-old.tar.gz"
|
|
echo "Would archive logs older than $days days to $LOG_ARCHIVE"
|
|
}
|
|
```
|
|
|
|
## Key Concepts
|
|
|
|
- **Permission-aware execution**: Different behavior for root vs normal user
|
|
- **String interpolation**: Building paths with `$HOME`, `$USER`
|
|
- **Loops for maintenance tasks**: Iterating over checks and retention periods
