Hi,

I have written a perl script but I don't know how to get the variables from a txt file. Actually, I can read the txt file in hash and get the variables but I have a small issue. In the txt file I have some paths that include variables.

The txt file with the variables looks like:

V1=/home/user
V2=$V1/test
V3=$V2/file.txt

[download]

I read the lines using:

Read variables
open my $vars, '<:utf8', "$Bin/vars.txt" or die $! ;

while (<$vars>) {

chomp;

my ($key, $value) = split(/=/, $_);
     $vars{$key} = $value;
    
}

my $V1 = $vars{'V1'};
my $V2 = $vars{'V2'};
my $V3 = $vars{'V3'};

print "$V1\n";
print "$V2\n";
print "$V3\n";

close ($vars);

The result that I get is:

/home/user
/$V1/test
/$V2/file.txt

but I want 

/home/user
/home/user/test
/home/user/test/file.txt

[download]

I would appreciate any help.
