Logging Terminal Tools
Log files record what a program did and when, from kernel messages and web server access logs to application output collected by syslog or the systemd journal.
Terminal tools in this category tail, filter, color and search that output, follow several files at once, and turn structured logs into readable tables. Sysadmins, developers and SREs use them to trace an error, watch a deployment or answer a question during an incident, often alongside observability and monitoring tools.
