Less is better, than tail

Jul 27 2009

I’ve been using tail to watch my log files for years:

tail -f log/production.log

It works great all the time, until you want to search for something, then you have to ctrl+c and open the file in less or vi.

Maybe there is a better way? After some googling, I found less is the answer:

less +F log/production.log

less +F works exactly like tail -f, with more:

  • Simply press ctrl+c to switch to editing model, so you can scroll backward and using any more/vi command, such as /pattern to search
  • Press shift+f again to switch back to tail model

Anyway, just run man less to find some more information.

Thinking

Jun 23 2009

If you think you are beaten, you are

If you think you dare not, you don’t,
If you like to win, but you think you can’t
It is almost certain you won’t.

If you think you’ll lose, you’re lost
For out of the world we find,
Success begins with a fellow’s will
It’s all in the state of mind.

If you think you are outclassed, you are
You’ve got to think high to rise,
You’ve got to be sure of yourself before
You can ever win a prize.

Life’s battles don’t always go
To the stronger or faster man,
But soon or late the man who wins
Is the man WHO THINKS HE CAN!
