Cool Executing Perl Script


Hello,

I'm new to linux/perl, and i have a little problem executing a perl script.

#!/usr/bin/perl -w
#

if ($^O eq "MSWin32")
{
$strProgram = "C:/Program Files/VMware/VMware VmPerl Scripting API/vmware-cmd.bat";
open(STDOUT, ">>C:\\VMware.log" );
open(STDERR, ">>C:\\VMware.log" );
}
else
{
$strProgram = "/usr/bin/vmware-cmd";
open(STDOUT, ">>/home/batch/VMware.log" );
open(STDERR, ">>/home/batch/VMware.log" );
}

$time = localtime(time);
die "Text" unless($ARGV[0]);

foreach (@ARGV) {
if ($_ eq "DebianTracVM")
{
$strVM = "C:\\TracVM\\TracVM\\Other Linux 2.4.x kernel.vmx";
}
elsif ($_ eq "Test")
{
$strVM = "/vmware/Test/Other Linux 2.6.x kernel.vmx";
}
else
{
die "Text"
}

@args = ($strProgram,$strVM,"start","hard");

$time = localtime;
print "$time Virtual Machine $_: ";
system (@args);

$time = localtime;
print "$time Virtual Machine $_: ";
@args = ($strProgram,$strVM,"getstate");
system (@args);
}

When i execute the perl script with "PowerOn.pl Test", i am getting the following error : -bash: PowerOn.pl: command not found.

Can anybody tell why i get this message?

When i execute the same script with "perl PowerOn.pl Test" everything works just fine.

Any help will be appreciated.

TIA

Not in PATH

How about ./PowerOn.pl Test ?

Starting the script with ./ works fine. What is the function of ./ when starting the script.

env | grep PATH

If your current directory is not there, then using ./ provides the path to your perl script. There are bits of wisdom of not putting all directories in your PATH, especially ".". This avoids security holes.

You've obviously chmod'd your perl script so it is executable,
chmod 777 PowerOn.pl

There's (usually) no need to let other people use your script, so make that

chmod u=rwx,go= PowerOn.pl
