Split a string into array in Perl

Question

my $line = \"file1.gz file2.gz file3.gz\";
my @abc = split(\'\', $line);
print \"@abc\\n\";

Expected output:

file1.gz
file2.gz
file3.gz         


        

Answer 1

Having $line as it is now, you can simply split the string based on at least one whitespace separator

my @answer = split(' ', $line); # creates an @answer array

then

print("@answer\n");               # print array on one line

or

print("$_\n") for (@answer);      # print each element on one line

I prefer using () for split, print and for.
