How to get different lines using a for loop
Hi
I am trying to write a small AWK program to extract 324 lines which have a pattern in the line numbers.
For examples, I want to extract lines 2, 5, 7, 11 and lines like (2+662), (5+662), (7+662), (11+662) and (2+662+662), (5+662+662), (7+662+662), (11+662+662) and so on for 27 times from 'File1'.
I wrote a code like
awk '{NR==i; for (i=2; i<=27; i+=662) print NR} {NR==i; for (i=5; i<=27; i+=662) print NR} {NR==i; for (i=5; i<=27; i+=662) print NR} {NR==i; for (i=11; i<=27; i+=662) print NR}' File1> File2
I think there are quite some flaws in my code.....Plese help

Hi there !
I need to treat files with variable line length, and process the tab-delimited words of each line. The tools I know are some basic bash scripting and sed ... I haven't got to python or perl yet.
So my file looks like this

NAME
bwild - Bacula's 'wildcard' engine
SYNOPSIS
bwild [options] -f <data-file>
DESCRIPTION
This manual page documents briefly the bwild command.
This is a simple program that will allow you to test wild-card expressions against a file of data.
OPTIONS
A summary of options is included below.
-? Show version and usage of program.
-d nn Set debug level to nn.
-dt Print timestamp in debug output
-f <data-file>
The data-file is a filename that contains lines of data to be matched (or not) against one or more patterns. When the program is
run, it will prompt you for a wild-card pattern, then apply it one line at a time against the data in the file. Each line that
matches will be printed preceded by its line number. You will then be prompted again for another pattern.
Enter an empty line for a pattern to terminate the program. You can print only lines that do not match by using the -n option, and
you can suppress printing of line numbers with the -l option.
-n Print lines that do not match
-l Suppress lines numbers.
-i use case insensitive match.
