String problem

[Cyril Jose]

Hello all,

I am trying to read characters in a string but I want to ignore the
first character and the newline at the end of the string, then store the
characters in between into a new variable:

str = ">Hello World\n"
new_var = " Hello World"

Any ideas to point me in the right direction?

str = ">Hello World\n"
str[1..-2] #=> "Hello World"

str = ">Hello World\n"
str[1..-2] #=> "Hello World"

Forgot to mention that I have a bunch of these types of strings of all
different lengths...thanks for the quick reply however!

">Hello World\n"[ /.(.*)/, 1]
==>"Hello World"
">Hello World\n".rstrip[ 1 .. -1]
==>"Hello World"

Hans's suggestion does work with different length strings

irb(main):001:0> 5.times {|i| s="a"+("b"*i)+"x";puts s, s[1..-2]}
ax

abx
b
abbx
bb
abbbx
bbb
abbbbx
bbbb
=> 5

Kind regards
