Perl Directory Manipulation

Perl Directory Manipulation

Perl provides several functions to create, delete, read, and manipulate directories. Here's a brief tutorial covering some of these functionalities:

1. Create a Directory:

You can create a directory using the mkdir function. It takes the directory path as a parameter:

mkdir("path/to/directory") or die "Failed to create directory: $!\n";

2. Delete a Directory:

You can delete a directory using the rmdir function. Like mkdir, it also takes the directory path as a parameter:

rmdir("path/to/directory") or die "Failed to delete directory: $!\n";

3. Check if Directory Exists:

You can check if a directory exists using the -d operator:

if (-d "path/to/directory") { print "Directory exists.\n"; } else { print "Directory does not exist.\n"; }

4. Read a Directory:

You can read the contents of a directory using the opendir, readdir, and closedir functions:

opendir(DIR, "path/to/directory") or die "Failed to open directory: $!\n"; while (my $file = readdir(DIR)) { print "$file\n"; } closedir(DIR);

opendir opens a directory for processing. readdir reads all files and directories in the opened directory, and closedir closes the directory handle after processing.

5. Change Working Directory:

You can change the working directory (the directory your Perl script is currently operating in) using the chdir function:

chdir("path/to/directory") or die "Failed to change directory: $!\n";

Remember to replace "path/to/directory" with your actual directory path. You can use a relative or an absolute path, depending on your needs.

The $! variable in die is a special Perl variable that contains the error message if an operation fails. It's very useful for debugging.
