When you want to remove a string  rather than replace it you can use String delete  or its mutator equivalent String delete    e g    x    foo nfoo  x delete    n     x now equals  foofoo   In this specific case String delete is more readable than gsub since you are not actually replacing the string with anything

You don t need a regex for this  Use tr    some text nandsomemore  tr   n

If you want or don t mind having all the leading and trailing whitespace from your string removed you can use the strip method        hello      strip      gt   hello       tgoodbye r n  strip      gt   goodbye    as mentioned here   edit The original title for this question was different  My answer is for the original question

Look here    How to replace multiple newlines in a row with one newline using Ruby

User · Answer

You need to use   n  not   n  in your gsub  The different quote marks behave differently   Double quotes   allow character expansion and expression interpolation ie  they let you use escaped control chars like  n to represent their true value  in this case  newline  and allow the use of   expression  so you can weave variables and  well  pretty much any ruby expression you like into the text   While on the other hand  single quotes   treat the string literally  so there s no expansion  replacement  interpolation or what have you   In this particular case  it s better to use either the  delete or  tr String method to delete the newlines   See here for more info
