Shell Programming and Scripting

Hi

can anyone help me understanding the following code

Code:

    my %config;
    open my $config, '<', 'config.txt' or die $!;
    while(<$config>) {
        chomp; 
        (my $key, my @value) = split /=/, $_;
        $config{$key} = join '=', @value;
    }

Hmm... Let me see if I can try...

1. create a hash called %config.
2. open the file "config.txt" or quit if can't open it. Open it to a scalar variable called $config. This is a little confusing. Now you have a hash and a scalar used as a file handle. Two different variables.
3. Using the file handle ($config) loop over each line of the file. This loads each line into $_
4. Remove the newline at end of each config.txt line (now in $_)
5. Parse the line. Put the FIRST field (fields separated by "=") into the variable $key, the rest goes into array @value... Config must look like "X=something, and more, and more" doesn't matter what's there, everything after the = goes into @value
6. Now load what was in config.txt into the HASH called %config. Put the KEY parsed in the line above into the hash index $config{$key} and the rest of the line (what ever was after the "=" in config.txt) into the data part of the hash....

How's that???

It's kind of funny that it splits on the "=" and then glues together the parts if there was more than one "=", when simply splitting only on the first "=" and leaving the others would literally have required only the addition of two characters.

suppose i have date in config file yahoo.com:200 .. how to get the data

I'm afraid I don't understand that question. If it's not directly related to the question above, perhaps you should start a new thread. Feel free to point back to this thread if it seems pertinent.

i got the answer

Thnaks a lot....
