Hi,

$ cat -A inp.file

option -A from command cat, show end line and no printable characters...

Theres no reason your awk script

awk '{print $0," "}' in > out

should not work. I see that your lines are 80 char long. Is it possible there's line wrapping occurring in your terminal/editor?

Yes you right, i tested it on a Mint Linux and it works!
Thank you guys.
