<0> hi all
<0> quick question -
<0> in perl will $list give the lenght of a lis @list?
<1> no, that#s $#list
<1> no, that's $#list
<1> and it'll give the scalar value of the last entry - so the length is $#list + 1
<0> hmn ok
<0> but $x=@list+1 will give you the lenght also?
<0> stored in x
<1> no
<1> for that, you'd use:
<1> my $x = $#list +1;
<0> huh
<1> then $x will contain the number of entries in @list
<0> im reading this book and it hasnt meantioned the $# at all is that a new feature?
<1> no, not at all
<1> it mentions scalar values for arrays?
<0> yeah
<1> well, $#list gives the scalar value of the last entry
<0> ok
<0> so i could do
<0> for($i=0; $i<$listOfWebsites; $i++){
<0> err $#listofwebsites
<0> then $x=$#listofwebsites[$i]
<0> well $#listofwebsites+1 right
<1> yeah
<0> cool thanks :)
<1> you want it to pull a specific site from a list?
<1> how i'd do that would be a foreach loop
<0> foreach($#listofwebsites) ??
<1> well, what do you need it to do?
<0> open each website and store the information to a file
<1> and the sites are stored in an array?
<0> yeah @listOfWebsites
<0> just as strings to be pased to wget
<1> so, you want it to go through the array, and for each and every entry, do something?
<0> yes
<1> that's even easier
<1> do it like this:
<1> foreach $site (@listofwebsites){
<1> do whatever you need to do
<1> }
<1> simple as that
<0> ahh and $site will hold each website?
<0> thats cool thanks man!
<1> yes
<1> no problem
<0> hello again
<0> how can you look at individual charecters in a string?
<2> I need perl to download a text file from a site and save it localy for parseing. anyone have some info that might help?
<3> Isn't there a www:get thingy or something?
<4> HTTP::Get ?
<3> That would be it.
<4> IO::Socket
<4> is this basically what you want ? http://www.newbie.org/snippets/cgi/content/sockets3.html
<3> If he's just getting a text file then HTTP::Get should be fine.
<2> i ended up useing LWP:UserAgent
<2> $ua->mirror($url);
<2> it automaticly compares the dates and only downloads if it's newer
<2> so it works perfect for what i'm doing
