In Perl, a directory is used to store values in the form of lists. A directory is quite similar to a file. Just like a file, the directory also allows performing several operations on it. These operations are used for the modification of an existing directory or creation of a new one. A directory can be very easily opened and processed using the built-in function glob. Glob: It returns a list of files that match the expression passed in the argument. This function can print all or the specific files whose extension has been passed to it. Syntax:
@list = <*>; // Prints all files in current directory @list = glob(“*.pl”); // Prints all files in current directory with extension .pl @list = glob(‘//GeeksforGeeks//Files//*); // Prints all files in the given path
Here are some examples that illustrate accessing a directory using File Globbing. Examples:
  • Accessing the current directory of the script:
    #!/usr/bin/perl -w
    # Accessing files using glob function
    @files = glob('*');      # Returns list of all files
    foreach $file (@files)   # Loop to run through all files
        print $file . "\n";     # Print all files
    Output: Glob Output1
  • Opening a specified directory:
    #!/usr/bin/perl -w
    # Prints only the filename excluding the path
    use File::Basename; 
    # Returns list of all files
    @files = glob('C:/Users/GeeksForGeeks/Folder/*'); 
    foreach $file (@files) # Loop to run through all files
        print basename($file), "\n"; # Print all files
