how to print all lines from a second match
I am trying to parse iostat output for io issues..
I want to print all lines including second occurance of 'extended' till EOF(end of file). Can we do that using awk or sed one liners or do we need a script for it?

I need to print the lines that do not match a pattern. I tried using grep -v and sed -n '/pattern/!p', but both of them are not working as I am passing the pattern as variable and it can be null some times.

IGAWK(1) Utility Commands IGAWK(1)
NAME
igawk - gawk with include files
SYNOPSIS
igawk [ all gawk options ] -f program-file [ -- ] file ...
igawk [ all gawk options ] [ -- ] program-text file ...
DESCRIPTION
Igawk is a simple shell script that adds the ability to have ``include files'' to gawk(1).
AWK programs for igawk are the same as for gawk, except that, in addition, you may have lines like
@include getopt.awk
in your program to include the file getopt.awk from either the current directory or one of the other directories in the search path.
OPTIONS
See gawk(1) for a full description of the AWK language and the options that gawk supports.
EXAMPLES
cat << EOF > test.awk
@include getopt.awk
BEGIN {
while (getopt(ARGC, ARGV, "am:q") != -1)
...
}
EOF
igawk -f test.awk
