Converting rows into multiple-rows
Hi every one;

I have a file with 22 rows and 13 columns which includes floating numbers.
I want to parse the file so that every five columns in the row would be a new record (row). For example, the first line in the old file should be converted into three lines with first two lines contain 5 fields and 3rd line with three fields. The process continues for all 22 lines.
The new file will have the following dimension: 66 rows and 5 columns.

Please help and let me know if you want more clarification.

input sample with two lines and 23 columns:
Code:
1  2  3   4  5  6   7  8  9 10 11 12 13
14 15 16 17 18 19 20 21 22 23 24 25 26

Expected output:
Code:
1  2  3  4   5
6  7  8  9  10
11 12 13
14 15 16 17 18
19 20 21 22 23
24 25 26

The output would have five columns (except records which are multiples of three since the each record in input file has 13 columns and 13%5=3).

Thanks

Use gawk, nawk or /usr/xpg4/bin/awk on Solaris.

Code:
awk '{ 
  for (i=1; i<=NF; i++)
    printf "%s", $i (!(i % 5) || i == NF ? RS : FS) 
    }' infile

Code:
awk 'function format(i){ retval=(i%5==0)?" %d\n":"%d "; return retval}
       {for(i=1;i<=13; i++) {printf(format(i),$i)} printf("\n") } ' oldfile > newfile

I like radulov's version better.

Small modification with the geeks sed solution should make ik work with tabs too:

Code:
sed 's/\([^ \t]\+[ \t]\+\)\{5\}/&\n/g' infile

-or-
Code:
sed -r 's/([^ \t]+[ \t]+){5}/&\n/g' infile
