How can I make this perl command check for subfolders as well?
To modify a Perl command to check for subfolders as well, you can use the File::Find
module, which provides a convenient way to traverse directories recursively. Here's an example:
perluse strict;
use warnings;
use File::Find;
# Specify the root directory
my $root_dir = 'path/to/root';
# Process files and subdirectories recursively
find(\&process_file, $root_dir);
# Callback function for processing each file or subdirectory
sub process_file {
my $file = $_;
my $full_path = $File::Find::name;
# Perform your desired operations on the file or subdirectory here
# Example: Print the full path of each file and subdirectory
print "$full_path\n";
}
In this example, you need to replace 'path/to/root'
with the actual root directory you want to traverse.
The find
function from File::Find
traverses the specified directory ($root_dir
) and its subdirectories recursively. It invokes the provided callback function (process_file
) for each file and subdirectory encountered.
Inside the process_file
function, you can perform your desired operations on each file or subdirectory. In the example, it simply prints the full path of each file and subdirectory encountered. Modify the function as per your specific requirements.
By utilizing the File::Find
module and its find
function, you can extend your Perl command to process files and subdirectories recursively.
