I'm using the
less to view log files. This is quite good, but I want to filter out some lines from output. E.g. I don't want to see lines containing "DEBUG" or I want see lines which contain only "[pool-9-thread-4]".
Is there easy way to do it? Is there any more advanced tool to work with log files?
I know solution as
grep 'pool-9-thread-4' my.log | less, but it is not good enough - I cannot change filtering criteria and it works slow for large files.
