tailspin

tailspin highlights log files without any setup. Dates, IP addresses,
URLs, UUIDs, numbers, paths and keywords like ERROR or WARN are colored
automatically. Output opens in a pager, or goes to stdout when piped.

Examples

tspin ./application.log

tspin --follow ./application.log

journalctl -f | tspin

The command is tspin, as upstream. If tspin is not found, run tailspin.tspin or create the alias:

sudo snap alias tailspin.tspin tspin

File access

tailspin can read files in your home directory. To also read USB drives
and other removable media (/media, /mnt), run:

sudo snap connect tailspin:removable-media

To read system logs in /var/log (for example /var/log/syslog), run:

sudo snap connect tailspin:log-observe
