Linux:shell:command: speed up 'grep'

'grep' is very slow when using it in a UTF-8 mode, specially for a large text file. However, it is fast if using 'C' mode. Use the command 'locale' to check the variable of 'LC_ALL'. Then

export LC_ALL="C"

(from http://tdas.wordpress.com/2008/02/03/speed-up-grep)

I tested it. The "C" mode is faster 50 times than the regular mode!

Software: Opera

Firefox released the version of 3.0, however, some favorite add-on are not avaible yet in the mean time. So currently I may not use firefox 3.0. However, a good alternate is opera. Actually I started to use opera since its version of 3.0, now the opera is pretty matual and extremely fast.

At the first, I didn't find how to find or search text in the page what you are browsering, which is not so convenient. Use ctrl+f just actives a window to allow you to search. I want a search function like one in Firefox. Yes, I just find it: use . to active it!
