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:
