Bad interpreter and end of line characters

ruby-talk
1

Hi all,

Check it:

# test1.rb - created via Eclipse on Windows, using UTF8 encoding
#!/usr/bin/ruby

# test2.rb - created via vi on Linux
#!/usr/bin/ruby

./test1.rb
: bad interpreter: No such file or directory

./test2.rb

Hey! WTF?

od test1.rb

0000000 020443 072457 071163 061057 067151 071057 061165 006571
0000020 000012
0000021

od test2.rb

0000000 020443 072457 071163 061057 067151 071057 061165 005171
0000020

Normally I can see newlines as ^M characters with vi, but I don't see
them, and attempting to replace them doesn't work.

According to my ASCII chart, 12 is a newline. Ok, I wrote test1.rb on
Windows. But where the heck is that 21 (device control 1?) coming from?
Is it the UTF8 encoding? And how do I get rid of it? And why is it
making Ruby choke?

Thanks,

Dan

od test1.rb

0000000 020443 072457 071163 061057 067151 071057 061165 006571
0000020 000012
0000021

Try

  cat -v test1.rb

or

  od -b test1.rb

Is it the UTF8 encoding? And how do I get rid of it? And why is it

   ruby -pi.bak -e '$_.sub!(/\cM$/, "")'
