rm -rf

I see some guys visiting my blog for rm -rf reference. I will write a short note on the usage of rm

Never, ever run this command: rm -rf /*

Combining with find:

[arun@om]$ find . -name "*.T" -exec grep -H "Hello" {} \;
./1.T:Hello
./Name/a.T: Hello Buddy;

To find and delete all the files under the current directory, having extension .T

[arun@om]$ find . -name "*.T" -exec rm {} \;

This is essentially, the power of find to fork rm process.
