In this guide, we will discuss the method of comparing the difference of two directories in Linux Mint 21.” Method of Comparing the Difference of Two Directories in Linux Mint 21 In this situation, it gets a bit difficult to differentiate between these directories. However, you might sometimes have two directories with pretty much similar content. Most people like to create a directory of all similar files. “Directories in Linux or any other operating system provide a very nice way to organize your files. I like Java a lot for this reason.Ģ27 /* * A class for comparing directories and high level file information on files in a directory.

What would have required coding is already free to use :0). Not only can I use key Strings, but also the class already provides a method called removeAll. In the end I only compare two collections, which is very easy using HashSets. If you are interested in the files, which are in synch / common between two directories use the method getCommonFileNames. The returned Set contains the key strings, which can be used for the HashMaps returned by the methods for getting the target and source file names and file paths.

The returned collection contains all file names, which.

Call method compareDir providing the target directory you want to compare against the source directory provided via construtors parameters.

fileExtension - a file extension, which should be used as filter for file types of interest.

pattern - a Pattern object for identifying files of interest.

dirPath - a path for a directory, which should be used as the source for comparisons.Create a new object of this class providing the following parameters.Source Code for comparing directoriesīelow a class, which is able to use a given regular expressions to compare file names in two given directories. Since I was not allowed to install new software on the machine and the workaround of using windows shell commands in combination with Excel and Regular Expressions was a bit annoying I deceided to implement a class in Java. Recently I had to compare the contents of two directories on Windows.
