perl - equal in if statement not working as expected -

- 

use text::diff; $count; our $stats2 = 0; for($count = 0; $count <= 1000; $count++){     $data_dir="archive/oswiostat/oracleapps.*dat";     $data_file= `ls -t $data_dir | head -1`;     chomp($data_file);     while(defined($data_file)){         print $data_file;         open (dat,$data_file) || die("could not open file! $!");         @stats1 = stat $data_file;         @raw_data=<dat>;         close(dat);         print "stats1 :$stats1[9]\n";         sleep(5);         print "checking $stats1[9] equals $stats2\n";         if(chomp($stats1[9]) != chomp($stats2)){             print "i here";             @diff = diff \@raw_data, $data_file, { style => "context" };             print @diff || die ("didn't see updates $!");         }         $stats2 = $stats1[9];         print "stat2: $stats2\n";     } }

output

[oracle@oracleapps osw]$ perl client_socket1.pl archive/oswiostat/oracleapps.localdomain_iostat_12.06.28.1900.datstats1 :1340925244 checking 1340925244 equals 0 stat2: 1340925244 archive/oswiostat/oracleapps.localdomain_iostat_12.06.28.1900.datstats1 :1340925298 checking 1340925298 equals 1340925244 stat2: 1340925298 archive/oswiostat/oracleapps.localdomain_iostat_12.06.28.1900.datstats1 :1340925304 checking 1340925304 equals 1340925298 stat2: 1340925304 archive/oswiostat/oracleapps.localdomain_iostat_12.06.28.1900.datstats1 :1340925304 checking 1340925304 equals 1340925304 stat2: 1340925304 archive/oswiostat/oracleapps.localdomain_iostat_12.06.28.1900.datstats1 :1340925304

as show in output when @stats1[9] not equal $stats2 should go if loop , print "i here" not working way. can please identify problem.

chomp() modifies string side-effect , returns linefeed deleted string, not modified string. want write

chomp $stats1[9]; chomp $stats2; if($stats1[9] != $stats2) {

c# - Copy ObservableCollection to another ObservableCollection -

how copy observablecollection item observablecollection without reference of first collection? here observablecollection item value changes affecting both collections. code private observablecollection<ratemodel> _allmetalrate = new observablecollection<ratemodel>(); private observablecollection<ratemodel> _metalrateondate = new observablecollection<ratemodel>(); public observablecollection<ratemodel> allmetalrate { { return this._allmetalrate; } set { this._allmetalrate = value; notifypropertychanged("metalrate"); } } public observablecollection<ratemodel> metalrateondate { { return this._metalrateondate; } set { this._metalrateondate = value; notifypropertychanged("metalrateondate"); } } foreach (var item in metalrateondate) allmetalrate.add(item); what causing , how can solve it? you need clone object referenced item before it's a...

All overlapping substrings matching a java regex -

-
is there api method returns (possibly overlapping) substrings match regular expression? for example, have text string: string t = 04/31 412-555-1235; , , have pattern: pattern p = new pattern("\\d\\d+"); matches strings of 2 or more characters. the matches are: 04, 31, 412, 555, 1235. how overlapping matches? i want code return: 04, 31, 41, 412, 12, 55, 555, 55, 12, 123, 1235, 23, 235, 35. theoretically should possible -- there obvious o(n^2) algorithm enumerates , checks substrings against pattern. edit rather enumerating substrings, safer use region(int start, int end) method in matcher . checking pattern against separate, extracted substring might change result of match (e.g. if there non-capturing group or word boundary check @ start/end of pattern). edit 2 actually, it's unclear whether region() expect zero-width matches. specification vague, , experiments yield disappointing results. for example: string line = "xx90xx"; strin...
