How to Grep for particular word and display..
Hi Guru's.... I've one log file in all my systems which writes the backup information..
I'have written a command like this:
ssh -l ora${sid} ${primaryhost} "tail -50 /oracle/$ORACLE_SID/newbackup/END_BACKUP.log" |grep 'insert' |tail -1| awk '{print $7}'
We have nearly 50 systems in our landscape, hence when i run this command the $7 would not work since the log file is saving in exactly in all the systems when i check i found the below three formats:
1.) insert into sapqd4.sdbah values ('20080808051812','net','QD4','DB','0','20080808054531','netbackup','netbackup')
2.) new 1: insert into sapqd1.sdbah values ('20080725011009','net','QD1','DB','0','20080725052004','netbackup','netbackup')
3.) new 1: insert into sapr3.sdbah values ('20080920182244','net','DB','0','20080921013618','netbackup')
Hence when i use the $7 the output is not accurate..
Now i would like to wirte a a command which only searches for ( and display the output..
Actual line:
new 1: insert into sapr3.sdbah values ('20080927210501','net','DB','0','20080928084821','netbackup')
Desired output:
('2008/09/27/ 21:05:01 ','net','DB',' 0 ',' 2008/09/28/ 08:48:21 ','netbackup')
The things which shown in read should not dispaly, the only ouput the i need is in black colour.
Any help would be greatfully appreciated..
Thanks in advance..

Mail::Mbox::MessageParser::Grep(3) User Contributed Perl Documentation Mail::Mbox::MessageParser::Grep(3)
NAME
Mail::Mbox::MessageParser::Grep - A GNU grep-based mbox folder reader
SYNOPSIS
#!/usr/bin/perl
use Mail::Mbox::MessageParser;
my $filename = 'mail/saved-mail';
my $filehandle = new FileHandle($filename);
my $folder_reader =
new Mail::Mbox::MessageParser( {
'file_name' => $filename,
'file_handle' => $filehandle,
'enable_grep' => 1,
} );
die $folder_reader unless ref $folder_reader;
# Any newlines or such before the start of the first email
my $prologue = $folder_reader->prologue;
print $prologue;
# This is the main loop. It's executed once for each email
while(!$folder_reader->end_of_file());
{
my $email = $folder_reader->read_next_email();
print $email;
}
DESCRIPTION
This module implements a GNU grep-based mbox folder reader. It can only be used when GNU grep is installed on the system. Users must not
instantiate this class directly--use Mail::Mbox::MessageParser instead. The base MessageParser module will automatically manage the use of
grep and non-grep implementations.
METHODS AND FUNCTIONS
The following methods and functions are specific to the Mail::Mbox::MessageParser::Grep package. For additional inherited ones, see the
Mail::Mbox::MessageParser documentation.
$ref = new( { 'file_name' => <mailbox file name>, 'file_handle' => <mailbox file handle> });
<file_name> - The full filename of the mailbox
<file_handle> - An opened file handle for the mailbox
The constructor for the class takes two parameters. The file_name parameter is the filename of the mailbox. The file_handle argument is
the opened file handle to the mailbox.
Returns a reference to a Mail::Mbox::MessageParser object, or a string describing the error.
