awk without printing newline

Question

I want the variable sum NR to be printed side-by-side in each iteration  How do we avoid awk from printing newline in each iteration   In my code a newline is printed by default in each iteration  for file in cg c ep c is c tau xhpl printf   n  file   gt  gt  to-plot xls     for f in 2 54 1 60 800          awk   sum   3   END   print  sum NR     file    f  v1 xls  gt  gt  to-plot-p xls     done done   I want the output to appear like this  cg c ans1  ans2  ans3   ep c ans1  ans2  ans3  is c ans1  ans2  ans3 tau  ans1  ans2  ans3  xhpl ans1  ans2  ans3   my current out put is like this    cg c   ans1 ans2 ans3   ep c   ans1 ans2 ans3   is c   ans1 ans2 ans3   tau   ans1 ans2 ans3   xhpl   ans1 ans2 ans3

You can simply use ORS dynamically like this   awk   ORS      print  1    2    3    4    5      ORS   n   print  6- 2  6    file in  gt  file out

I guess many people are entering in this question looking for a way to avoid the new line in awk  Thus  I am going to offer a solution to just that  since the answer to the specific context was already solved   In awk  print automatically inserts a ORS after printing  ORS stands for  output record separator  and defaults to the new line  So whenever you say print  hi  awk prints  hi    new line   This can be changed in two different ways  using an empty ORS or using printf   Using an empty ORS  awk -v ORS   1   lt  lt  lt   hello man    This returns  helloman   all together   The problem here is that not all awks accept setting an empty ORS  so you probably have to set another record separator   awk -v ORS  -    print       file   For example   awk -v ORS  -   1   lt  lt  lt   hello man    Returns  hello-man-    Using printf  preferable   While print attaches ORS after the record  printf does not  Thus  printf  hello  just prints  hello   nothing else     awk  BEGIN print  hello   print  bye    hello bye   awk  BEGIN printf  hello   printf  bye    hellobye   Finally  note that in general this misses a final new line  so that the shell prompt will be in the same line as the last line of the output  To clean this  use END  print     so a new line will be printed after all the processing     seq 5   awk   printf   s    0   12345         prompt here    seq 5   awk   printf   s    0  END  print      12345

awk   sum   3   END   printf   f  sum NR     file    f  v1 xls  gt  gt  to-plot-p xls  print will insert a newline by default  You dont want that to happen  hence use printf instead

If Perl is an option  here is a solution using fedorqui s example   seq 5   perl -ne  chomp  print        END print   n     Explanation  chomp removes the newline print       prints each line  appending a space the END   block is used to print a newline  output   1 2 3 4 5

The ORS  output record separator  variable in AWK defaults to   n  and is printed after every line   You can change it to     in the BEGIN section if you want everything printed consecutively
