Regex: Anchor to Line End ($)
EasyRegular Expressions3-5 minThe brief
Extract lines that END with '.log' from /root/work/files.txt into /root/work/out.txt.
Be precise about the ending: 'app.log.bak' finishes with '.bak', not '.log', so it must not appear in your output.
What you'll do
- out.txt holds exactly the lines ending in '.log'
