Tailing two log files
Solution 1:
Yes, tail outputs lines appended to all the files given on the command line:
tail -F sqlLogs.log perflogs.log | egrep '(sql-time|exec-time)'
Solution 2:
Have a look at MultiTail. It's your friend.
You can have the multiple log tails in
- different windows, a al vim's 'split' - or have it merge the two (or N) streams into one view and - you can filter steams by regex and, if you like, - it will 'tee' the output to a file
