sed to change some values in a file permanently

Hi,
I have a file where I there are some 1500 lines and in there I want to change some values. For that I am using sed like below:

PHP Code:




cat /home/test.css | grep "network.type” | sed –i ‘s/0/1/’

Now the problem is it changes the lines in file but how to make it permanent and if I use sed with -i option then I have to provide the file name with it but I am using grep to grep the line.

Any clue please.

You don't need cat, nor grep - use sed's address facility (see the manpage). Something like this

Code:

sed -i /network.type/s/0/1' test.css
