Try changing the line below to:

by default Net::Ping uses UDP packets, but not all hosts will respond to

I think it lies in the history of programming. Traditionally for loops look
like this (when written in perl)
for($i=1; $i=100; $i++){

If I have a string and the first character is a space,
may not always be a space.
Example: John
Tommy
Beth
John and Beth have a space, Tommy does not.
How do I strip that. I do not want to use the global
command because a want the space between First

my @arr = ( This has a leading space, This does not );
foreach my $string (@arr ) {
$string =~ s/^\s//;
print $string, \n;
}
prints:
This has a leading space
This does not
The regular expression
s/^\s//;
means
s/ # substitute
^ # at the beginning of the string
\s
Tanton Gibbs [[EMAIL PROTECTED]] quoth:

*The regular expression
*s/^\s//;
s/^\s+//g; would be even better as it would remove all whitspace at the
beginning of a line and it would replace all matches to the pattern
instead of just the first it finds.

The perlsyn doc says that foreach is a synonym for for, so the two are
indeed interchangable. But you should also note that there are 2 different
modes in which the for/foreach statement works.
If you use it in the C-style for($x=1; $x10; $x++) {} way, then $x is not
localized to the loop
All I have to say is... (perldoc perlsyn; goto line 145)
The following compound statements may be used to control
flow:
if (EXPR) BLOCK
if (EXPR) BLOCK else BLOCK
if (EXPR) BLOCK elsif (EXPR) BLOCK ... else BLOCK
LABEL while (EXPR) BLOCK
You should change the line
die Device::SerialPort Aborted without match\n unless (defined $data);
