Question

I writing a ksh shell script and I have long comma separated string that I need to divide into separate lines only after the 9th comma. After the 9th comma, I want to remove that comma and make a new line:

For Example:
Initial String
1,2,3,4,5,6,7,8,9,10,11,12,13,14,14,15,16,17,18,19,20,21

Output:

1,2,3,4,5,6,7,8,9,10
11,12,13,14,14,15,16,17,18,19,20
21

I know this is possible with awk but I am not so familiar with command. Can someone please provide how to do this

Thanks

Answer 1

$ s='1,2,3,4,5,6,7,8,9,10,11,12,13,14,15,16,17,18,19,20,21'

$ print "$s" | tr , '\n' | paste -d , - - - - - - - - - - | sed -e 's/,\+$//'
1,2,3,4,5,6,7,8,9,10
11,12,13,14,15,16,17,18,19,20
21

$ print "$s" | tr , '\n' | xargs -n 10 echo | tr " " ,
1,2,3,4,5,6,7,8,9,10
11,12,13,14,15,16,17,18,19,20
