### Script tidies up the output of commands like "df"
### and "ls", where file and disk sizes allow bigger 
### values than the format strings are expecting.
###
### The script loads the standard input into an array,
### and looks for the maximum width of each column.
### It then prints out the array, using the maximum width
### in the formatting string.
###
### eg. df -k | ac
###

BEGIN{
           maxf = 0
}
{
           for(i=0;i<=NF;i++){
                     arr[NR,i] = $i
                     if ( NF > maxf ) maxf = NF
                     if ( length($i) > maxl[i] ) maxl[i] = length($i)
           }
}
END{
           for(x=0;x<=NR;x++){
                     for(y=o;y<=maxf;y++){
                               printf("%-"maxl[y]"s ", arr[x,y])
                     }
                     printf("\n")
           }
