reformat output of cat /proc/scsi/scsi

hello,

if i run command

Code:

mybox:~> cat /proc/scsi/scsi
Attached devices:
Host: scsi0 Channel: 00 Id: 00 Lun: 00
  Vendor: MATSHITA Model: DVD-RAM UJ-860H  Rev: 1.02
  Type:   CD-ROM                           ANSI  SCSI revision: 05
Host: scsi2 Channel: 00 Id: 00 Lun: 00
  Vendor: ATA      Model: FUJITSU MHY2120B Rev: 890B
  Type:   Direct-Access                    ANSI  SCSI revision: 05

i'm using php to iterate all scsi devices in my system, how to format the output of cat /proc/scsi/scsi to return scsi host and vendor in the following format (similar to 'lsscsi' command);

Code:

0 0 0 0    MATSHITA DVD-RAM UJ-860H
2 0 0 0    ATA      FUJITSU MHY2120B

it is easy if i'm on linux 2.6 as i have 'lsscsi' which output;

Code:

khairil@box4:~/drivers> lsscsi
[0:0:0:0]    cd/dvd  MATSHITA DVD-RAM UJ-860H  1.02  /dev/sr0
[2:0:0:0]    disk    ATA      FUJITSU MHY2120B 890B  /dev/sda

thx.

Code:

<?php
$cmd = `cat /proc/scsi/scsi`;
$patternhost = "/Host:\s+scsi(\d+)\s+Channel:\s+(\d+)\s+Id:\s+(\d+)\s+Lun:\s+(\d+)/Ums";
$patternvendor = "/Vendor:(.*)\s+Model:(.*)\s+Rev.*/Ums";
preg_match_all($patternhost,$cmd,$hostmatch);
print_r($hostmatch);
preg_match_all($patternvendor,$cmd,$vendormatch);
print_r($vendormatch);
?>

I leave it to you to grab the array elements and format them to your needs.
