Examples
1. View the most recent CUPS log:
cupsd-logs
2. View a specific log by number:
cupsd-logs -n 10
3. Search for logs containing the term "error":
cupsd-logs --search=error
4. Display logs from a specific date range:
cupsd-logs --start-date=2023-01-01 --end-date=2023-01-31
5. Change the directory where CUPS logs are stored:
cupsd-logs --log-dir=/var/log/custom-cups-logs
Common Issues
1. No logs are being displayed:
- Ensure that the CUPS service is running and generating logs.
- Check the value of the
--log-dir
option and make sure it points to the correct directory.
2. Search results are incomplete:
- Verify that the
--search
query is correct and specific. - Try using a different search term or broadening the search criteria.
Integration
cupsd-logs can be integrated with other Linux commands to perform more advanced tasks:
- grep: Filter logs based on specific patterns (
cupsd-logs | grep "error"
). - awk: Extract specific information from logs (
cupsd-logs | awk '{print $3}'
). - sort: Sort logs by date, time, or other criteria (
cupsd-logs | sort -nk3
).
