Ok, let's say that you're looking to delete the word 'hello' from all files in the directory /home/me/txt:

Code:

find /home/me/txt | xargs sed 's/hello//g'

In one directory:

Code:

sed -i 's/hello//g' *

To search by content in the entire system is a bit messy---is that really what you need to do?

"find" is not good for searching by content......
