I would like to change the way I display a big (~6000 lines) log file using wim, less or whatever, in order to simplify the problem checking.

I'd like to highlight some line of the log based on a patter (i.e. error, warning, info...) and/or hide some others.

Which tools could I use? Do I just need a shell script? It's important that after the process, I can read the output using less, vim, ... to perform search operations!

Edit: a little piece of the log:
