[Help] PERL Script - grep multiple lines
Hi Gurus,
I need some help with the "grep" command or whatever command that you think suitable for me. I'm about to write a perl script to extract a report from the system and submit it to the end users. The input for the script will consist of 3 element.
1) Generation ID
2) Month
3) Year
I have a text file that contain the following data :
*Its actually quite a long data (from 2001 to 2008) but the format are the same
*
I need to get those 3 element for the input in my perl script. The main element is Generation <ID#>. Let say from the sample data above, i want the data with the date of Jan 2001 to let say Dec 2001, in order to get the Generation ID#, i need to search for all the JAN to DEC 2001's Generation ID#.
So the question is, how can i do that ?
Thanks,

ZGREP(1) General Commands Manual ZGREP(1)
NAME
zgrep - search possibly compressed files for a regular expression
SYNOPSIS
zgrep [ grep_options ] [ -e ] pattern filename...
DESCRIPTION
Zgrep invokes grep on compressed or gzipped files. These grep options will cause zgrep to terminate with an error code:
(-[drRzZ]|--di*|--exc*|--inc*|--rec*|--nu*). All other options specified are passed directly to grep. If no file is specified, then the
standard input is decompressed if necessary and fed to grep. Otherwise the given files are uncompressed if necessary and fed to grep.
If the GREP environment variable is set, zgrep uses it as the grep program to be invoked.
EXIT CODE
2 - An option that is not supported was specified.
