Hi,
I have a bunch of files that I want to convert from CRLF to just LF.
How might I do this? I’m testing with the following example file
(steel.rb):
f = File.new(“steel”, “w”)
f.syswrite(“steel\ncity”);
f.close
I then run this from cygwin and get the following output
Ben A.@andersonbd1 /cygdrive/c/ruby
$ ruby steel.rb
Ben A.@andersonbd1 /cygdrive/c/ruby
$ cat -v steel
steel^M
city
How might I get rid of the CR and just have ruby use an LF?
Thanks,
Ben

Try in “binary” mode.
f = File.new(“steel”, “wb”)
BTW, if you use blocks, you can omit the f.close:
File.new(“steel”, “wb”) do |f|
f.print(“steel\ncity”)
end
(See also IO#binmode )

Perhaps it makes a difference which binary you use, windows vs.
cygwin. I am usign the cygwin Ruby and it did not exhibit the
behavior you mentioned.

Just as in many other languages, use “wb” instead of “w”.

Bill K.:
File.new(“steel”, “wb”) do |f|
f.print(“steel\ncity”)
end

Ooops! Thanks for catching that! O:-)
