Top Forums UNIX for Dummies Questions & Answers Dividing a column by it's first number Post 302538175 by bartus11 on Tuesday 12th of July 2011 03:20:45 AM

The above script is not dividing by first column, but multiplying. To multiply by 119th column use:
Code:
#!/usr/bin/perl
open I,"$ARGV[0]";
chomp(@x=<I>);
for ($i=0;$i<=$#x;$i++){
  @y=split / +/,$x[$i];
  for ($j=0;$j<=$#y;$j++){
    push @{$c[$j]},$y[$j];
  }
}
for ($i=0;$i<=$#y;$i++){
  for $j (@{$c[$i]}){
    $d[$i]=$j if ($j!=0 && !$d[$i]);
  }
  @one=grep {$_ == 1} @{$c[$i]};
  if ($#one==$#{$c[$i]}){
    @{$c_out[$i]}=map {("0")} @{$c[$i]};
  } else {
    for ($j=0;$j<=$#{$c[$i]};$j++){
      $c_out[$i][$j]=$c[118][$j]*$c[$i][$j];
    }
  }
}
for ($i=0;$i<=$#x;$i++){
  for ($j=0;$j<=$#y;$j++){
    if ($j<2){
      print $c[$j][$i],"  ";
    } else {
      print $c_out[$j][$i],"  ";
    }
  }
  print "\n";
}

WCWIDTH(3)						   BSD Library Functions Manual 						WCWIDTH(3)

NAME
wcwidth -- number of column positions of a wide-character code LIBRARY
Standard C Library (libc, -lc) SYNOPSIS
#include <wchar.h> int wcwidth(wchar_t wc); DESCRIPTION
The wcwidth() function determines the number of column positions required to display the wide character wc. RETURN VALUES
The wcwidth() function returns 0 if the wc argument is a null wide character (L''), -1 if wc is not printable, otherwise it returns the number of column positions the character occupies. EXAMPLES
This code fragment reads text from standard input and breaks lines that are more than 20 column positions wide, similar to the fold(1) util- ity: wint_t ch; int column, w; column = 0; while ((ch = getwchar()) != WEOF) { w = wcwidth(ch); if (w > 0 && column + w >= 20) { putwchar(L' '); column = 0; } putwchar(ch); if (ch == L' ') column = 0; else if (w > 0) column += w; } SEE ALSO
iswprint(3), wcswidth(3) STANDARDS
The wcwidth() function conforms to IEEE Std 1003.1-2001 (``POSIX.1''). BSD
