What is the easiest way to print all a list's elements separated by line feeds in Perl?
972
When you specify a newline character in this context, make sure to surround it with double quotes, not single quotes, or a backslash and an ``n'' will be used to join the pieces of the array. Thus, to print the numbers from 1 to 10, each on a single line, you could use the following perl statement: print join("\n",1..
In Perl, the splice() function is used to remove and return a certain number of elements from an array. A list of elements can be inserted in place of the removed elements. Syntax: splice(@array, offset, length, replacement_list) Parameters: @array – The array in consideration.
Perl newline and tab examples print "Here is a tab\t"; print "Here is a form feed\f"; print "Finally, here's a bell a newline\a\n"; As a practical matter, it's very common to print Perl newline characters, and it's relatively common to print tab characters.
print() operator – print operator in Perl is used to print the values of the expressions in a List passed to it as an argument. Print operator prints whatever is passed to it as an argument whether it be a string, a number, a variable or anything. Double-quotes(“”) is used as a delimiter to this operator.
print "$_\n" for @list;
In Perl 5.10:
say for @list;
Another way:
print join("\n", @list), "\n";
Or (5.10):
say join "\n", @list;
Or how about:
print map { "$_\n" } @list;
Why not abuse Perl's global variables instead
local $\ = "\n";
local $, = "\n";
print @array;
If you get excited for unnecessary variable interpolation feel free to use this version instead:
local $" = "\n";
print "@array\n";
