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 nlinux     sed   a N s  n   g    removes only Ist new line character  I somewhere found this command    printf   new nto nlinux     sed   a N   ba s  n   g    but it gives   ba  Event not found    if i do   printf   new nto nlinux     sed   a N s  n   g    sed   a N s  n   g    then it gives correct output but i am looking for something better as i am not sure how many new character i will get when i run the script  incoming stream is from echo or printf or some variable in script  Thanks in advance

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

This might work for you   printf   new nto nlinux     paste -sd                 new to linux    or   printf   new nto nlinux     tr   n                   new to linux    or   printf   new nto nlinux    sed -e   a  -e       -e  N  -e  ba  -e     -e  s  n   g   new to linux
