Trying out grep and am confused as hell
I am using $user to save time.
Is this a valid method? xx is the file with contents

Code:
grep –i xx $user

So form what am reading I need to use pipes (new to me)

Code:
grep –n xx

will display the line numbers?

And
Code:
grep –I $user

should check for the current username in the file.

Do I need an other grep command to start from from line 1?

So I can use an if statement to check if the users is in the file, if so do the following:

Code:
 grep –n xx | grep –I $user | grep '^1' | >> newfile


Any feedback would be great ^^
