Script

Prashant Zanwar_2 — Fri, 05 Mar 2004 09:32:35 GMT

Hi,

I have a file which is having 1000 Line text.

1st line is header line.

I want to make an another file using this file adding some text "A" in beginning of each line avoiding header.

I want to automate this through the script. I want to provide file as input to the script.

Please reply immediate, as this is some urgent requirement.

Thanks in advance

Regards
Prashant

Using awk;

awk '{if (NR == 1) {print} else {print "EXTRA"$0}}' FILE

eg if your file contains

HEADER
BODY
BODY
BODY

The above awk will generate

HEADER
EXTRABODY
EXTRABODY
EXTRABODY

with perl you can do

$perl -pale 'next if ($. == 1); s/^/new/g' file1 > file2

This skips the first line, adds new to the beginning of the rest of the lines. And
creates file2.

Just a change to the previous awk;

awk '{if (NR == 1) {print} else {print "EXTRA;"$0}}' FILE
