Take a look at `perldoc -f open` for a complete answer to this question. This will do what you want: `open(my $handle,">>","sample.txt") or die("Cannot write to file: $!\n");` Note that this uses the three-argument version of open and uses a lexical variable as a filehandle, both are recommended best practices and you should stick to them (see the perldoc for why).

I want to open that file for writing in "append" mode. And just to be different, try this: `#!/usr/bin/perl -wT use strict; use Tie::File; my @ry; tie @ry,"Tie::File","myfile.txt" or die $!; push @ry,"stuff"; untie @ry; exit(0);` [download] In Perl there is always more than one solution to a problem.... and nobody expects the Perl Inquisition! update: fixed minor typo pointed out by Happy-the-monk Peter L.

Hey devlele, You have to use operator ">>" while opening. If you want to open in R+W mode you just put the "+" operator infront as "+>> $fileName". You better go through the help pages of "open" function. You also take a look at the "seek" function, that will help you to handle the file pointers effectively. Regards, S.Venni Rajan.
