You'll notice that the file must be in that exact location in order to work. If the script is ever moved or your home directory ever changes, that require statement will stop working. Instead of absolute paths, it's often common to create a. Actively scan device characteristics for identification.
Use precise geolocation data. Select personalised content. Create a personalised content profile. Measure ad performance. Select basic ads. So if the directory is really huge, it can make a performance difference.
Under normal circumstances you wouldn't notice, but under stress conditions, it can absolutely matter. This is my favorite method for being easy to read: Dir. SimplGy SimplGy What in this code prevents directories from also being used with fname 's iterations?

Returns true if the named file is an empty directory, false if it is not a directory or non-empty. Returns an array containing all of the filenames in the given directory. Calls the block once for each entry in the named directory, passing the filename of each entry as a parameter to the block.
Expands pattern , which is a pattern string or an Array of pattern strings, and returns an array containing the matching filenames. If a block is given, calls the block once for each matching filename, passing the filename as a parameter to the block.
The optional base keyword argument specifies the base directory for interpreting relative pathnames instead of the current working directory. As the results are not prefixed with the base directory name in this case, you will need to prepend the base directory name if you want real paths.
The results which matched single wildcard or character set are sorted in binary ascending order, unless false is given as the optional sort keyword argument. The order of an Array of pattern strings and braces are preserved. Note that the pattern is not a regexp, it's closer to a shell glob. See File::fnmatch for the meaning of the flags parameter.
Matches any file. Can be restricted by other values in the glob. Note, this will not match Unix-like hidden files dotfiles. Matches any one character in set. Matches either literal p or literal q. Equivalent to pattern alternation in regexp. Matching literals may be more than one character in length.
