UNIX for Dummies Questions & Answers

hey guys...

Im looking to do the following:
1
2
3
4
5
6
7
8
9

Change to:
1 4 7
2 5 8
3 6 9

Did use | perl -lpe'$\=$.%3?$":"\n"' , but it doesnt give me the matrix i want.

Any help please?

Thanx

Try...

Code:

awk '{a[NR%3+1]=a[NR%3+1]" "$0}  END {for (i in a){print a[i]}}' inputfile

Thanx, That almost worked...

But the output to your code yields:
3 6 9
1 4 7
2 5 8

So i just fiddled with it a bit and came up with

1 4 7
2 5 8
3 6 9

using awk '{a[NR%2+2]=a[NR%3+1]" "$0} END {for (i in a){print a[i]}}' inputfile, but i hav one open line at the beginning of the file
