modify a particular pattern starting from second line of the search pattern
Hi,
I am new to this forum and i would like to get help in this issue. I have a file 1.txt as shown: apple banana orange apple grapes banana orange grapes orange .... Now i would like to search for pattern say apple or orange and then put a # at the beginning of the pattern from second line i.e, for the first matched pattern/first line ignore and then from second matched pattern/second line and so on put a # at the beginning of the pattern. Your help is appreciated. Thanks. |
