Search String, Replace the entire raw with a new string

Ruby
1

Hi,

I need a script which does the following.

  1. Searches for multiple strings in a file
  2. Replace the entire raws which contain those strings with a new
    string.

Thanks.

Below example only replaces the exact regex string, but I need it to
replace the entire row which contains that string.

file_names = [‘file.txt’]

file_names.each do |file_name|
text = File.read(file_name)
new_contents = text.gsub(/regex_string/, “new_string”)
File.open(file_name, “w”) {|file| file.puts new_contents }

end

You could look this up easily enough in the Regex documentation:
“^” is the start of a line
“$” is the end of a line
“.*” is any set of characters excluding newlines, except in multiline
mode.

/^.regex_string.$/

Thank you very much. The issue was already resolved the same way.
