# tail
## General
### See updates to log files as they roll in:
- `tail -f`
### How to do a `tail -f` of log rotated files?
https://unix.stackexchange.com/questions/22698/how-to-do-a-tail-f-of-log-rotated-files
Use `tail -F` instead.
The `-F` option tells `tail` to track changes to the file by filename, instead of using the inode number which changes during rotation. It will also keep trying to open the file if it's not present.
### Filter [[tail]] log outputs with [[ripgrep]]
```bash
tail -n 20 -f log/daemon_rCURRENT.log | rg INFO
```
