 replacement and then write the file, I have used File::slurp and works for

 processing and come out with error. I have also used Tie::file module same 
 case as not processing, any guidance.

Hi,


have you try this kind of command :

  perl -p -i -e s/oneThing/otherThing/g yourFile

hang or not ?


and, 500MB is not a gigantic file :)

 Try:
 
 push @Cylinders, [ $1, $2 ];
 
 This will put the two captured variables in an anonymous array and push 
 it onto @Cylinders.

so simple !!

thanks :)

2 dimensions array

2011-12-11 Thread kurtz le pirate 

Hello,

I want to have a two dim array. I build it like this:
  
  my @Cylinders;


  /.*(.*),(.*).*/;
  push @{$Cylinders[0]}, $1;
  push @{$Cylinders[1]}, $2;


Seems to work but a get an array with '2' lines and 'n' columns  
instead of 'n' lines with '2' columns'.


display array with 'print Dumper \@Cylinders;' confirm this.

where is my mistake ?



thank if you can help me.

 Hi,
 
 I am a newbie to perl.
 I have an array which has few elements like '1,2,3,4,2,3,1,2,1,1,1,4,6,7'
 i need to know how many times each element has occurred in the same array.
 for example 1-5 times
   2-3 times...
 could some one throw some light on how i can do this.
 thanks in advance..

quick write, not tested :

my @array = (1,2,3,4,2,3,1,2,1,1,1,4,6,7);
my @freq;

for (@array) { $freq[$_]++;}
  
my $i=0;
for (@freq) {
  print $i : $_ times\n;
  $i++;
  }
