Configuration files has been discussed previously, for instance here, and here. Super Search is a good way to find answers on perlmonks. Andreas	[reply]

See How do I post a question effectively? Generally, you'll find that people here will go out of their way to avoid writing your program for you — they might even offer to present their "rate card." Normally you would present code that you wrote that doesn't work and ask about it. Or ask how to approach a problem. Things like that. However... `my %o; open my $in, "abc.properties" or die $!; while(<$in>) { $o{$1}=$2 while m/(\S+)=(\S+)/g; } close $in;` [download] -Paul	[reply] [d/l]

If you want to read things inside a file, as if the text inside it is config data- you want to use something like YAML to code with. If what you want is to be able to associate metadata (like the filename) onto a file, any kind of file- you can use File::Attributes::Extended or File::PathInfo::Ext	[reply]

I just added following code to print value of each value...but it was blank.. Any reason why?? `my %o; open my $in, "file.properties" or die $!; while(<$in>) { $o{$1}=$2 while m/(\S+)=(\S+)/g; print "$1 and $2"; } close $in;` [download]	[reply] [d/l]

So, what does `file.properties` look like? If the file exists but it empty, your script will not produce any output but will not fail either. If the file contains at least one line, your program will output at least one line containing the word "`and`". Note that the following line implies that you expect more than one `key=value` pair per line: `$o{$1}=$2 while m/(\S+)=(\S+)/g;` [download] Is that really what your configuration file looks like?

Maybe your input file (file.properties) is not what you think it is. Show use a few lines of it. This works for me: `use warnings; use strict; my %o; while (<DATA>) { $o{$1}=$2 while m/(\S+)=(\S+)/g; print "$1 and $2\n"; } __DATA__ name=ant password=gilly level=5` [download] Prints: `name and ant password and gilly level and 5` [download] See also: use strict and warnings Basic debugging checklist	[reply] [d/l] [select]
