Hello. Just want to know how to use special character in Regular Expression. I wish to remove all the carrier returns from a text file, I can use: tr -d "\r" < text_file > modified_text_file But if I do: sed -i s/\r//g text_file it actually removes all the character "r" from the file. This is also a problem in vi(1). Besides <CR> I wish to manipulate tabstops and line-feeds with RE too.home | help
