removing new line character from incoming stream using sed

Question

I am new to shell scripting and i am trying to remove new line character from each line using SED. this is what i have done so far :

printf \"{new\\nto\\nlin         


        

Answer 1

To remove newlines, use tr:

tr -d '\n'

If you want to replace each newline with a single space:

tr '\n' ' '

The error ba: Event not found is coming from csh, and is due to csh trying to match !ba in your history list. You can escape the ! and write the command:

sed ':a;N;$\!ba;s/\n/ /g'  # Suitable for csh only!!

but sed is the wrong tool for this, and you would be better off using a shell that handles quoted strings more reasonably. That is, stop using csh and start using bash.
