Hi all,
I want to do this :
open(hndr, "/home/manjain/.bash_profile");
open(hndw, ">", "/home/manjain/bashrc.copy");
while ($nextline = )
{
$nextline =~ s/manjain/\$USER/g;
print(hndw, $nextline); #problem here
}
But perl refuses to take a comma between hndw and $next

You should *always* verify that the files opened correctly before trying

Dear List,
I've been struggeling with the following:
#!/usr/bin/perl
use strict;
use warnings;
my $ip = ("127.0.0.255");
if ($ip =~ /127\.0\.0\.[2..254]/) {
print "IP Matched!\n";;
} else {
print "No Match!\n";
}
For a reason i don't understand:
127.0.0.1 doesn't match as expected...
Eve
But it accept!

print "Hello", " ", "World!", "\n";

In your case you are just using the wrong syntax for optional file handle..

to use, for example, $x = "abc" and $y = "ABC" so something like
y/$x/$y/;
behave like

The tr/// operator doesn't interpolate so you have to do something like:
eval y/$x/$y/;
Or perhaps:

why are you putting single chars inside a char class? [\d] is the same
as \d and [1] is just 1.
