This has been discussed very recently, and an Awk solution was presented. Here's a Ruby one:
Code:
ruby -F, -lane '
BEGIN{$a=[]};$a.concat([$F]);END{$a.transpose.each{|x|puts x.join(",")}}
' infile

1,2,3,4
5,6,7,8

becomes

1,5
2,6
3,7
4,8

shell script to tranpose rows to columns

Following Shell script works...
There should be a file namely "data" with following content
Code:
1,2,3
4,5,6
7,8,9

then after running the script the content of file will be
Code:
1,4,7
2,5,8
3,6,9


Code:
num=$(awk -F"," 'NR==1 { print NF }' data)
print $num

i=1
while (( $i <= $num ))
do
newline=''
for val in $(cut -d"," -f$i data)
do
newline=$newline$val","
done
nline=`print ${newline%?}`
print $nline >> tmpdata
(( i = i + 1 ))
done
mv tmpdata data

see if it works

Put this is a file - testawk.awk
Code:
BEGIN {FS=","}

{
for (i=1;i<=NF;i++)
{
 arr[NR,i]=$i;
 if(big <= NF)
  big=NF;
 }
}
 
END {
  for(i=1;i<=big;i++)
   {
    for(j=1;j<=NR;j++)
    {
     printf("%s\t",arr[j,i]);
    }
    printf("\n");
   }
}

awk -f testawk.awk testfile
