Is there a chomp like Perl operator in Ruby using which I can literally  
remove new line characters as show below in my Perl script:

use strict;  
use warnings;

my $str1 = “Hello\n”;  
my $str2 = “World”;  
print $str1.$str2;

print “\n”;

chomp($str1);

print $str1.$str2;

print “\n”;

Any clue?

There’s a really easy way to answer this question for yourself:

## $ ri chomp (from ruby core) Implementation from String

str.chomp(separator=$/) =\> new\_str

* * *

Returns a new String with the given record separator removed from the  
end of str (if present). If $/ has not been changed from the  
default Ruby record separator, then chomp also removes carriage return  
characters (that is it will remove n, r, and r\n).

The online docs (plus a few examples) for the method Ben showed the ri  
of  
[http://ruby-doc.org/core/classes/String.html#M000819](http://ruby-doc.org/core/classes/String.html#M000819)

Thanks it worked:

str=“Hello\n”  
str2=“World”

puts str+str2

str1=str.chomp

puts str1+str2

Not the whole story. If you know you’re not going to use the original  
string,  
you might consider chomp! instead.
