With the awk suggestion there may be a missing newline at the end, rendering the output an improper Unix format. This could be corrected:
Code:
awk 'END{if(NR%3) printf RS} {ORS=NR%3?FS:RS}1'

--
And for completeness, the inevitable :
Code:
paste -d" " - - - < file

is another one

Or with:
bash code:
  1. #!/bin/bash
  2. STR="1
  3. 2
  4. 3
  5. 4
  6. 5
  7. 6
  8. 7
  9. 8
  10. 9
  11. 10
  12. 11"
  13.  
  14. NR=2 ## 0, 1 , 2 = 3 items in a row
  15. C=0
  16.  
  17. for n in $STR;do
  18.     if &#91; $C -eq $NR ]
  19.     then    printf "%s\n" "$n"
  20.     else    printf "%s " "$n"
  21.     fi
  22.     ((C++))
  23.     &#91; $C -gt $NR ] && C=0
  24. done
  25. printf "\n"
  26. exit 0
