bash - \n in variable in heredoc -


Is there a Bash Hurdock to explain '\ n \' in a headlock?

I have got an archetype string in a loop for word1 word2 word3t in TCP_avr = $ i rate = "$ rate \ n $ tmp_avar" 

  / Pre> 
 And then I want to use the string created in a Hurdock:  
  cat & lt; & Lt; EOF & gt; Myfile HEADER == $ ret == Trailer EOF  
 
 However, I would like to interpret "\ n" the character as a new line, so that output is 
 
  Header == Word 1 word2 word3 == trailer  
 
 instead of 
 
  HEADER == \ nword1 \ nword2 \ nword3 == trailer  
 
 Is this possible? Or should I possibly build my initial string in any way?

You can use $ 'in Bash \ n' one To add a new line to the string: 

  ret = "$ ret" $ '\ n' "$ TMP_VAR"

You can also use + = for: 

  ret + = $ "\ n '" $ TMP_VAR "
