Hi Scripting Gurus, I am new bee in perl, and trying to write a script which must print the free disk space availability of C and E drives. Please advice.
Here is the script snippet and expected output:
#!/usr/bin/perl
use CGI qw/:html3 :standard/;
$spaceuselog = "E:\\admin\\VOBSpaceUsage\\vobspaceusage.log.txt";
$report = "E:\\admin\\VOBSpaceUsage\\vobspaceusage.html";
open(LOG, ">$report") || die "ERROR writing to logfile $logfile!";
$datetime=localtime();
$count=0;
$vob="";
$vobsize=0;
$totalvobsize+=0;
$vd="";
$sum=0;
#@vobs = `ct lsvob -s -host blrcc1`;
@vobs= ("
\\scm_blr_amor", "
\\scm_blr_projects", "
\\scm_blr_misc", "
\\blr_mobile_projects", "
\\blr_mobile_test");
if ($ENV{OS} =~ m/Windows/)
{
$store = $ENV{SystemDrive};
open (VSU, ">$report") or die "Cannot Open:$!\n";
open (VS, ">>$report") or die "Cannot Open:$!\n";
$ct = "cleartool";
}
else
{
open (VSU, ">E:\\admin\\VOBSpaceUsage\\vobspaceusage.html") or die "Cannot Open:$!\n";
$ct = "C:\\Program Files\\Rational\\ClearCase\\bin\\cleartool.exe";
}
push (@vsu, start_html("Vob Space Usage Report"),"\n");
push (@vsu, "<p><b>VOB Backup Process Completed Successfully on Backup Server: <font color=blue>BLRSTG01</font color></b>");
push (@vsu, "<p>The VOBs are backed-up and available at the location:
\\blrstg01\Clearcase\Backups folder.</p>");
push (@vsu, "\n<td width=auto align=center>======================================================================================= =\n");
push (@vsu, "<p><b>VOB Size Status on VOB Server: <font color=blue>BLRCC1 </font color></b></p>");
push (@vsu, "<table border=1 width=auto>\n");
push (@vsu, "<tr>\n");
push (@vsu, "<td width=auto align=center><b>Vob Name</b></td>\n");
push (@vsu, "<td width=auto align=center><b>Size in Mb</b></td>\n");
push (@vsu, "<td width=auto align=center><b>Size in Gb</b></td>\n");
push (@vsu, "</tr>\n");
push (@vs, "</table>");
foreach $vob (@vobs)
{
$vobname=$vob;
chomp($vobname);
push (@vsu, "<tr>\n");
push (@vsu, "<td width=auto align=left> $vobname </td>\n");
@vbpath= `ct lsvob $vob`;
foreach $path (@vbpath)
{
# print "\n$path";
$path =~ s/\*//;
$path =~ s/\s//;
# print "\n$path";
if ($path =~ /\s(\\\\[A-Za-z\\a-z0-9\_\.\\]*)/)
{
#print "\nVOBPATH --> $1 \n";
$cdft = "$1\\c\\cdft";
#print LOG "\t$cdft";
$ddft = "$1\\d\\ddft";
#print LOG "\t$ddft";
$db = "$1\\db";
#print LOG "\t$db";
$sdft = "$1\\s\\sdft";
#print "\n Source Pool ---> $sdft";
$vobpath = $1;
#print "\nVOBPath>>>>>>>$vobpath";
}
}
@totspace = `diruse /m $vobpath`;
@a=split(" ",$totspace[-1]);
$totalvobsize = $a[0];
# print LOG "\t\t$totalvobsize";
push (@vsu, "<td width=auto align=center> $totalvobsize </td>\n");
$totalGBsize = ($totalvobsize / 1024);
# print LOG "\t\t$totalGBsize";
push (@vsu, "<td width=auto align=center> $totalGBsize </td>\n");
}
#push (@vs, "<p>Disk Usage of <b>C</b> Drive</p>\n");
#push (@vs, "<p>Disk Usage of <b>E</b> Drive(VOBs Storage included)</p>\n");
#foreach(@msg)
#{
# print $_;
#}
foreach (@vsu)
{
print LOG;
}
#push (@vsu, <table>);
foreach (@vs)
{
print LOG;
print RLOG;
}
open (RLOG, "<E:\\Backups\\log\\rlog.txt");
@rlog = <RLOG>;
for( @rlog ){
# print if /Disk Usage/ .. 0
push (@du, $_) if /Disk Usage/ .. 0
}
$seen =1;
foreach $line(@du)
{
# @new= split(/\s/,$_);
chomp($line);
# print "\n$line";
if (($line =~ /^[0-9]*/) && ($line =~ /free$/))
{
@val = split(/\s/,$line);
$new = $val[0];
$new = sprintf "%.2f", $new;
# print "\nI am processing C drive info, The value of new variable is $new";
if ($new < 100.00)
{
print "\nThe Free space on BLRCC1 C drive is less than 100 GB, Please Upgrade/Free some space on the disk";
}
# else
# {
print "\nThe available free space on BLRCC1 C drive is $new";
# }
$val[0] = 0;
$seen=0;
}
$seen=2;
# print "\nLooped :$seen \n";
if (($line =~ /^[0-9]*/) && ($line =~ /free$/) && ($seen ==2))
{
@val = split(/\s/,$line);
$raghu = $val[0];
# print "\nValue is $val[0] \n";
$raghu = sprintf "%.2f", $raghu;
# print "\nI am processing E drive info, The value of new variable is $raghu";
if ($raghu < 100.00)
{
print "\nThe Free space on BLRCC1 E drive is less than 100 GB, Please Upgrade/Free some space on the disk";
}
# else
# {
print "\nThe available free space on BLRCC1 E drive is $raghu";
# }
}
print LOG "<p>$line</p>";
push (@vs, "<p>$line</p>\n");
}
close RLOG;
close LOG;
close VS;
close VSU;
Right now I am getting the output as shown below:
The available free space on BLRCC1 C drive is 103.82
The available free space on BLRCC1 E drive is 103.82
The available free space on BLRCC1 C drive is 145.17
The available free space on BLRCC1 E drive is 145.17
Expected output :
The available free space on BLRCC1 C drive is 103.82
The available free space on BLRCC1 E drive is 145.17
