Align the values in column properly
This is my input,is it possible to do a bit of scripting on this to produce a properly alligned output.

I/P
Code:
-0.015 0.021 0.056 0.073 0.061 0.020 -0.038
-0.090 -0.113 -0.091 -0.025 0.064 0.141 0.170
0.130 0.027 -0.106 -0.215 -0.249 -0.181 -0.024
0.169 0.319 0.356 0.245 0.011 -0.262 -0.465
-0.497 -0.322 0.017 0.398 0.664 0.682 0.412
-0.073 -0.595 -0.934 -0.920 -0.511 0.174 0.877
1.300 1.224 0.611 -0.347 -1.286 -1.800 -1.609
-0.696 0.646 1.897 2.501 2.100 0.719 -1.188
-2.866 -3.537 -2.733 -0.552 2.279 4.603 5.245
3.519 -0.357 -5.125 -8.708 -8.786 -3.555 7.563
23.529 41.762 58.733 70.895 75.704 72.376 62.138
47.862 33.187 21.390 14.372 12.105 12.694 13.068
10.065 1.538 -12.849 -31.426 -50.960 -67.603 -78.021
-80.350 -74.675 -62.911 -48.148 -33.699 -22.165 -14.821



O/P should like this
Code:
 aaa.bb aaa.bb -cvbgh.kl
-ccc.vb   jjh.jk         0.00

that is decimal point point should be in a single line,whatsoever the values start with

Thanks in advance

come again... didn't get you...
show us a sample output from your input...

Code:
awk '{printf ("%8.3f %8.3f %8.3f %8.3f .....etc\n", $1, $2, $3, ...)}'

You get a noddy badge if you do it with purely using shell-builtins and without spawning a process for every line of input.

Hi Ahamed,
Sorry,the format got disturbed and its really hard to understand....
well i try to make it bit clear.
the output should not be dodgy as the i/p is, it should be bit aligned....
say after the decimal there are two digits(always) & how about if those two digits always follow a single staright line vertcally top to bottom...

thus all the values(irrespective of signs or number of digits will look properly aligned.),as if they are propely formatted.

Hope that makes sense.

Hi Indra2011,

hartz's answer is correct. I will write the complete and working command. I hope it helps.

Yeah, hartz solution will work.

I tried with %5.3f and it didn't work, so I thought it will never work and starting ended making this awk script .
When I was about to paste it, I saw birei's post. hee hee.

I am posting my awk code anyways. It will prefix zero's to make the number in proper format.

Code:
awk '
{ 
        for(i=1;i<=NF;i++){
                a[++k]=$i;
                split($i,_1,".");
                l=length(_1[1]);
                (l>max)?max=l:l=0;
                if(i==NF){
                        a[++k]=xxxx;
                }
        }
}
END {
        for(i=1;i<=k;i++){
                if(a[i] == xxxx){
                        printf "\n";
                        continue;
                }
                split(a[i],_2,".");
                l=length(_2[1]);
                net=max-l;
                if(net > 0){
                        while(net>0){
                                val=val"0";
                                net--;
                        }
                        sub(/^-/,"-"val,a[i]) || sub(/^/,val,a[i])
                        val=""
                }
                printf a[i]" "
        }

}' input_file
