arrays - basic perl: regex statement not working in perl 5.10.1 machine but works in 5.18? -


I'm testing the following code that compares the words of a string and searches for matches problem only code In the lower part of the regex statement, it does not produce any results / matches on the Linux server in the school which is going to run / test me, on which Perl 5.10.1 is used. Does it work fine on strawberry pearl for some reason on my local windows machine?

Is there any other way that the Regex statement given below can be modified, to get the same result on the earlier versions of Perl (or have I made a mistake somewhere)? 

  Strict use; Use warnings; Use data: Dumper; My $ keyword_file = "keywords.txt"; # It changes for an array @keywords My $ myString = "This string will be logged in later; print"; #read Keywords my @keywords; Open (FH, "$ keyword_file") or die "Can not open $ keyword_file to read: $!"; While (& lt; FH & gt;) {chomp; Push (@keywords, $ _); } Close FH or die "$ keyword_file can not be closed: $!"; #compare Keywords and File String Foreign Currency (@keywords) {if ($ myString = ~ / $ _ /) {# has problems here & lt; ********** match ";}}   
 The keyword file is just a simple text file that contains a word like print, .. etc ..  
 keywords.txt:  
  Exit ls print grep    
 
 
 On the Windows made you use Windows CR LF as the line end, then you can do this in Unix system without converting the end of the line to Unix Line Ending (LF). S It means that instead of just  exit  instead of  $ _  in  exit  one cart refund.  < P> Fix the end of the line (eg using  dos2unix ), or on Unix system (windows   s / \ s + \ z  Handling Windows files on  Change ).

The circuit has the following specifications: The present value of swift SW15-0 on the D2 board should be shown in four hexadecimal four sections of HEX3-0. This part of the circuit will be combination logic. To use an active-less asynchronous reset and KEY1 to use KEY0 as the clock input, you must store SW15-0in in a 16-bit register in the value The register should be enabled to have a 16-bit positive edge, which uses the embedded D flip-flo
