I stand by my reply to this post. Sure, unpack is quicker. But if you use
regex, i always prefer to use my own defined
i think what you really want to use then is chomp or a regexp..
or you'd have to say
print hello\n
print \b
print world
etc

Hello,
I know I can use the backspace character to overwrite previous characters and

Please use the the 'use lib' pragma, rather then fiddling with @INC
concider:
use lib (../foo);
rather than:
BEGIN: { push @INC, '../foo' }
perldoc lib for more info

because push @INC is a runtime statement,
use lib is a compile time statement
meaning you'll be alerted if the dir doesnt exist, or something else goes wrong at the
moment you start your script, rather then it dying half way when not findin a file.

Hello
you might want to try to use 'chomp' on your variable... this function
is specifically there to 'chomp off' trailing newlines
you'll often see it used as:
open FH, 'foo.txt';
while(FH){
chomp; #remove trailing newline
do something
}
perldoc -f chomp for details
hth,

How do you mean?
concider:
if ('a' == 'b') { print foo } # this will print 'foo', seeing 'a' and 'b' both yield
'1' in numeric
context here.
however
$x = 'a';
print $x + 4;
will print '4';

Converting 'a' to a number gives 0.

you can print them out as a csv file as follows:

on that note, you can also use the getopt module, that lets you specify
switches like you're used to on any linux system as follows:
script.pl -i input.txt -o output.txt

maybe there's a more elegant way, but this will work:

open O, output.txt;

login name is 'foo', your home dir will by default be, /home/foo

Stephane, what you are looking for is the LWP module.. it comes standard
with any ActiveState perl release but is not standard with Linux (or at
least RedHat)
try search.cpan.org if you need to obtain and look for LWP
you'll find the documentation very informational.
