in reply to concatenating text files before reading

Hi Hossein,
I need to read several (small) text files (all files in same dir)
look into using opendir to open your directory, then you can use readdir to get your files to read, using open.
However, one need ask; Is the ORDERing of your files contained in your directory important? If so, you might have to sort your file in a way to get the final content in the a correct order.
* The content of all files are supose to go into one scalar $content
You can initialize a string say my $content = ""; then when you open and read through each of the files, chomping the newlines from each lines you can concatenate like so

... while(my $line = <$fh>){ chomp $line; $content .= $line; }
* Update.

If you tell me, I'll forget.
If you show me, I'll remember.
if you involve me, I'll understand.

[choroba]: Why don't they use tire chains?
[perldigious]: First snow, probably not prepared right away choroba.
[stevieb]: it's Quebec... they do weird stuff there :) In the mountains, it is *mandatory* for trucks to use tire chains. Many passenger vehicles do as well (but it's not mandatory for them)
[perldigious]: That stuff can hit fast... like what we just got where I'm at. Saw a few people who had slid OUT of the roundabout I have to drive through to get to work, not used to the ice yet, take awhile to get the hang of it again and make vehicle adjustments.
[stevieb]: man, when the roads are glare ice, I don't even bother going to work or out... unless I absolutely have to, or was already out in the first place
[choroba]: Tire chains are mandatory here in mountains, and the only unprepared each year are gritters
[stevieb]: I have a 3 day winter survival kit in my vehicle in the event I get snowed in in the mountains (which has happened before due to avalanches closing the roads (and once in the summer due to a massive forest fire that trapped us
[perldigious]: a handful of people in my work area did not make it, but I live pretty close and it's flat the whole way, so I didn't have any trouble. The roundabout is the worst thing I have to negotiate.
[thezip]: G'day all!
[perldigious]: Well, that and dodging the people who forget how ice works right away. :-)
