Sorry for the late reply (meetings...

)

(assume awkscript filename = SmellsLikeHomeWork.awk)

Code:


{
  if (c!=FILENAME) { c=FILENAME ; i++ ;j=0 }
  a[i,++j] = $5
}


END {
    for( n=1 ; n<=j ; n++)
    {
      for( m=1 ; m<=i ; m++ )
      {
        printf("%s ",a[m,n]);
      }
      printf("\n");
    }
}

Usage: nawk -f SmellsLikeHomeWork.awk file1 file2 file3 file4

This should do:

Code:

awk '{print $5}' $(ls -1 file* |sort -n -k1.5) |pr -t -s" " -184

184 is the no. of files. The reason behind the "$(ls -1 file* |sort -n -k1.5)" is to get the files in correct alphabetical order (it skips 'file' and sorts on 1, 2, 3...). If your filenames are not following a regular pattern, then you may need to put them manually in the correct order like this:

Code:

awk '{print $5}' f1 file2 filename3 |pr -t -s" " -3

I don't think its used often but sometimes its just what you need.
