in reply to Re^4: pattern search in all the files in a directory
in thread pattern search in all the files in a directory

  • The perl function chomp chomps $_ if variables are omitted i.e chomp($_) can be written simply as chomp;
  • Use 3 argument open function and also check the return of the open function like so
    open my $fh, "<", $file_name or die "can't open file: $!"; while(<$fh>){ chomp; ... } ...

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