| Hi,
I need to concatenate 2 arrays like that:
@list=glob('*.txt');
@list.=glob('*.log');
But it doesn't work.
Have I missed anything please?
Thanks And Best Regards,
Eliyah

The . is the *string* concatenation operator. It evaluates both its
arguments in a scalar context.
You simply want to add values to the end of the array. That's what the
push() function does.
perldoc -f push
my @list = glob('*.txt');
push @list, glob('*.log');
Alternatively, if you want syntax more consistant with concatenation:
my @list = glob('*.txt');
@list = (@list, glob('*.log'));
But I would never use that in real life. Use push().
