How do I scan dmesg contonusly for warning or fatal messages

Hello,
- How do I scan dmesg continuously for warning or fatal messages and mail the lines containing the errors to someone.
- I presume a script can be used.
- How can this process involked at system startup ?
Thanks

I can help with the scanning part at least:

tail -f /var/log/yourlog | grep "errorcode to lookfor" > output.txt

(or something VERY similar to above..) lookup above commands for exact syntax and examples.

I'm sure theres a way to grab that file when theres a change, if theres not a command for it its probably more advanced scripting than I can help with. I do email out log files to myself using a "mail" command after similar setup as above logs program output (backups, etc).

grep -i '(warning|error|fatal|something)' /var/log/messages | mail -s error_logs your@address.com

Besides you can set up logwatch.
