i have to rewrite a script in order to be compatible with file lines  
ending by CR instead of unix \n

my script is simple, it take the content of a folder and merge the file  
all together in a unique file, those files have CR lines ending and such  
must be the merged file.

what to do in that case ?

You could do something like

# untested

File.open(“result.txt”, “wb”) do |out|  
Dir["\*"].each do |file|  
File.open(file) do |in|  
in.each\_line do |line|  
line.chomp!  
out.write(line)  
out.write("\r\n")  
end  
end  
end  
end

Kind regards

```

If you need to work line-by-line instad of slurping them (which would  
be easier and line-ending agnostic), then pass CR as the optional  
separator to your line-oriented idiom. For example

cr\_text\_file.each("\015") do |cr\_line|  
# …  
end

– fxn
