Noob question about matching texts
 

hi all, I'm totally new to linux, and have a big problem!

I have multiple configuration files and some other files that contain an email that its line should be deleted.

it can be like this:

filexxxx:
...
Created By:xxxxx@domain.com Date-Created:03/04/09 @ 04:34:28 AM CST Status:Flagged For xxxx
...


so I want to find files contains xxxx@domain.com, and delete its matching line automaticaly in all my HDD.

what can I do?

I think the command you are looking for is sed.
Something like:
sed -i '/xxxxx@domain.com/ d' *
But that doesn't work on the test box I have access to here. It says -i isn't a valid option (online man page disagrees).
Also, that would only work on the current directory. Not sure if sed can be made to work on the entire filesystem.

Sorry. Not a concrete answer, but a direction to look in at least :-)

thanks wolfger.

but it didnt work in my box too.

is there any other suggestions?
