Print in Perl shows leading spaces for each item.

I upload a file to an array (each line in an array element). I process the elements of the array and save it in a new file. I want to print a new file:

print ("Array: @myArray");

But - he shows them with leading spaces in each line. Is there an easy way to print an array without initial spaces?

Matt Fenwick is true. When your array is in double quotation marks, Perl will put a value $"(by default it is a space, see man perlvar ) between the elements. You can simply put it outside the quotation marks:

print ('Array: ', @myArray);

If you want the elements to be separated, for example, with a comma, change the output field separator:

use English '-no_match_vars';
$OUTPUT_FIELD_SEPARATOR = ',';     # or "\n" etc.
print ('Array: ', @myArray);

- join:

my $delimiter = '';  # empty string

my $string = join($delimiter, @myArray);

print "Array: $string";
