In Perl, you can get the file path through the built-in __FILE__ literal, which returns the full path and filename of the current script. Here is an example:
#!/usr/bin/perl
use strict;
use warnings;
my $file_path = __FILE__;
print "The file path is: $file_path\n";
This code will output:
The file path is: /path/to/my/script.pl
Alternatively, Perl also provides the Cwd module which enables you to get the full path of a file using its relative path. Here is an example:
#!/usr/bin/perl
use strict;
use warnings;
use Cwd;
my $relative_path = "my_folder/my_file.txt";
my $file_path = Cwd::abs_path($relative_path);
print "The file path is: $file_path\n";
This code will output something like:
The file path is: /path/to/my_folder/my_file.txt
Both methods will return the full path to the script or file.
