Remove only TRAILING whitespace

Ruby

Is there any way to only remove trailing white space from a string. I
have tried to use strip but that will also take off leading white space
and I want to keep that.

any help is appreciated

String#rstrip will remove just the white space on the end (the “right”
side) of the string. Likewise, String#lstrip removes leading white
space only. And you already know about String#strip. :wink:

str = " string "

rightTrim = str.rstrip
=> " string"

for completeness

leftTrim = str.lstrip
=> "string "
