Re: [Ask] About awk

[Morning Star <morning.star.crew@gmail.com>]

Thanks, Mark. You saved my time. It works for me if I change the initial i to 1 (i=1), because I don't want to get $0 to be the output.  

Greetings,

Marco

Marco,

Does the following work for you?

BEGIN {
    splitat = 3
}
{
    for (i = 0; i <= NF; i++) {
        printf("%s ",$i)
        if ((i % splitat) == 0) printf("\n")
    }
}

Put into a file called split.awk and run with "awk -f split.awk your_input_file_name".
