Perl syntax

Query with perl syntax

Aim: is to change a perl script to use a new file

I was required to replace
- entries \"$entries\"
with
-lib <full_path_to_filename>

So in the code detector.pm
Code:
sub rundetector
{
        my $class = shift;

        mkdir($resultDirectory);
        my @coFiles = glob($inputFile);
        foreach my $coFile (@coFiles)
        {
                $logger->info("Running detector on $coFile.");
                system("Detector -entries \"$entries\" -nolow -no_is -parallel $processorCount -dir $resultDirectory $coFile");
        }
}


I replaced

Code:
system("Detector -lib  $source/version2/files/imread.txt  -nolow -no_is -parallel $processorCount -dir $resultDirectory $coFile");
        }

Is there a syntax error?
or does it have to be

Code:
  system("Detector -lib  \"$source/version2/files/imread.txt \" -nolow -no_is -parallel $processorCount -dir $resultDirectory $coFile");
        }

The second is safer, in case one of your variables has spaces in it, but you have an extra space in there which will mess it up.

Code:
system("Detector -lib  \"$source/version2/files/imread.txt\" -nolow -no_is -parallel $processorCount -dir $resultDirectory $coFile");

thanks but does the file imread.txt have to be in the same place where the code is stored?

Basically we have a config file wherin we mention all the source files and use that to run the script.
The source files are usually placed in a different directory altogether

can this file remain in that location where all the files are placed and it would be called using this same code ?

or do i need to place this particular file in the same location of code for it to run properly?

That depends on the application being used.
