I have used this command sparingly in the past and I recently learnt more options by solving couple of my problems. I really don’t know whether grep is the right choice here, but hey! it worked :-)

Last week Zite suggested this article, I’ve known about Linus and his rude comments. But reading this article, I realised that being polite is not right solution for everything. Having the experience of working with the many developers over the years, I met only very few people who act on subtle comments I pass during discussion about code/best practices. The rest just ignore and do what they have always been doing.
