AWK-grep from line number to the end of file
Does anyone know how to use awk to act like grep from a particular line number to the end of file? I am using Solaris 10 and I don't have any GNU products installed.
Say I want to print all occurrences of red starting at line 3 to the end of file.
EXAMPLE FILE:
red
green
red
red
yellow
green
So the ouput should be:
red
red

Hi Folks,
Using the Vi, how can I add a numbers at the end of the line.
For eg: I have the numbers in the file as:
58.125.33
22.58.68
25.144.225
114.25.38
I need to add .0/8 at the end of all the line. So, it should be like
58.125.33.0/8
22.58.68.0/8
25.144.225.0/8
114.25.38.0/8 (6 Replies)

for each line number found I want to output this line number of file B.
