Ok I did as you said:
Code:
data=`cat $2 | xargs -n $1`
#echo $data
columns=$1
i=1
echo $columns
while [ "$columns" -gt 0 ]
do
awk_cmd=`awk -v i=$1 '{sum+=$i} END {print sum/NR}'`
echo "$data | $awk_cmd"
i=`expr $i + 1`
columns=`expr $columns - 1`
done
But then I get this kind of error:
>> sh reader4 4 testfil.txt
awk: syntax error near line 1
awk: bailing out near line 1
2 2 1 1
1 1 1 1 |
awk: syntax error near line 1

1 1 1 1 |

2 2 1 1
1 1 1 1 |
What I want is that is goes through each column on each run in the while loop and prints the corresponding average. But I really appreciate the help, I have been to some forums where you get slammered because, maybe, stupid questions.
