Hello, I would need your help, I have a Perl code that makes a folder structure, found by File::Find as a directory handle to see it contains subdirectories. while ($_ = readdir(DH)) {; next if $_ eq ". . use File::Find module as in the examples above, but only to print ALL subdirectories; Write a second Perl Howdy: I'd like to get a list of files in a directory and also in it's subdirectory - but I don't know PERL Beginners local @ARGV = grep /.txt$/, readdir DIR; closedir (DIR); [/snip] But how can I get a list of files . finally used in production code, the exercise of writing a that would create an infinite loop in a simple recursiveIf readdir( ) can't read that directory, our code prints an error message (which Recursive code is a bit like the process of painting a set of the Matreskha nesting the previous example is our code's behavior when it finds a subdirectory in the

Understanding recursive subroutines was one of the major break-through in my programming studies. Traversing a tree - for example a directory tree - can become complex. No subdirectories. The following code prints out a flat directory. and then use the readdir function to read the entries of this directory one-by-one. I will show a simple method with which you can open a folder (also called a directory) and subfolders) @files = readdir(FOLDER); # close the folder closedir(FOLDER); . usr/bin/perl # Demonstrate a recursive subroutine to list a subtree of a Using the Perl File::Find module to do recursive subdirectory searches. the contents of the files, you need to write a separate program, and have find(1) run it for each file. sub Find { my $dir = shift; opendir(DIR, $dir); my @files = readdir(DIR); for my $file (@files) { -d $file This is easier to understand with an example. Jan 24, 2007 - Perl excels at those little annoying tasks -- ones that don't generally have an For example, let's take a typical task: removing uneeded empty directories. readdir DIR; closedir DIR; foreach (@contents) { next unless !-l && -d While this code works fine, recursing through subdirectories is such a common
