Dear all,
I have a text file call access.log and it contains about 5030 lines.
Some lines contain some keyword, e.g. "ricky ng".
How can I delete all the entries that contain "ricky ng" line and
write to a new file call access.trace.log.
I know we can use strstr() function.
But, I don't know how to use strstr() function.
Pls help me.
Thanks!
