I want to assign the each column of the following file in a separate
variable.

For this I used the following code
#!/usr/bin/perl -w
@arr1 = qw/java oracle/;
@arr2 = `ps -eo pid,user,pcpu,pmem,args | grep -v grep | grep $arr1[1]`;
$length= $#arr2;
for($i=0;$i<=$length;$i++)
{
chomp;
$val=$arr2[$i];
#print $val."\n";
@arr = split(/\s+/,$val);
print $arr[1]."\n";
But I am not getting the desired output.
This may work better:
#!/usr/bin/perl
use warnings;
use strict;
my $user = 'oracle';
open my $ps, '-|', 'ps', '-eo', 'pid,user,pcpu,pmem,args'
or die "Cannot open 'ps' pipe: $!";
while ( my $line = <$ps> ) {
my @fields = split ' ', $line, 5;
print $fields[ 1 ] if $fields[ 1 ] eq $user;
}
close $ps or warn $! ? "Error closing 'ps' pipe: $!"
: "Exit status $? from 'ps'";
__END__
