Gathering Logs: I keep my notes in dated folders like this
2010/02/_log.txt
It is a temporal style system where things can slowly fade into history but are still searchable and readily retrievable. When I want to browse through my log notes I just run this.
find . -name \_log.txt | xargs cat | less
Find is recursive by default. The xargs tips the stack of filenames on its side for the cat command. And less gives me vim-like navigability. Couple this with an alias and I’ve got an easy way to go back in time.
