![]() Meld supports file editing, filtering with regular expressions, comparing and merging three files, and comparing two or three folders and their contents, and also provides helpful visualization of differences using arrows and color-coding. A cool thing about Meld is that you don’t have to install it – just run the executable and use it as a portable app. You can download the source and the Windows version, and find the package in the repositories if you’re a Ubuntu, Fedora or SUSE user. Meld packs features from other diff tools into a Python-built interface. This might turn away some users luckily, they can choose another tool from this list since they all offer more or less the same options. Diffmerge is free, but it will occasionally ask for a paid registration key. The settings dialog lets you define custom rules for handling various file types. It can compare up to three files and two folders and show if the files are identical, which can be useful when checking if an rsync backup was performed correctly. You can edit files within Diffmerge, automatically merge file versions and export differences to a new file. This application works on Linux, Windows and OS X, integrates well with Windows Explorer, and offers installer packages for some distributions. Diffuse works on Linux, Windows and Mac OS X. It also supports (limited) syntax highlighting and offers integration with several version control systems – including Git, Mercurial and Subversion – to help you keep files in sync. You can edit files directly from Diffuse and perform merges and line matching. It can compare an unlimited number of files in a side-by-side view and summarize the differences. The great thing about Kdiff3 is that it lets you paste text from any file directly into the main window, eliminating the need for creating files when you just want to compare text “on-the-fly.” DiffuseĪt first sight it seems simple, but Diffuse is as equally powerful as other tools on this list. You can toggle word wrap and line numbers for better overview and adjust color settings to mark the differences. The “Settings -> Configure Kdiff3” dialog lets you set parameters for file comparison in folders (by date, size, binary comparison, or full contents) and between files (ignore case, numbers and white space). Kdiff3 integrates well with KDE (supports Dolphin service menus), but it will work on all Linux distributions, Windows and Mac OS X. ![]() It lets you compare two files to a base file, and merge, split and join entire folders, files or just selected parts of text. Kdiff3 is a graphical frontend to diff, meaning that it relies on diff and offers all its options. You can also use it to merge files, and it works with compressed files, too.īoth text editors have relatively complex syntax that requires some learning, but it pays off since they’re very powerful and thoroughly customizable. Similarly to Vim, Emacs can show files in separate windows, side by side, and highlight the differences. You can configure how to split each window for a better overview.Įmacs users can choose between a diff extension (called “major mode”) or Ediff, a slightly more advanced mode that lets you interactively change compared files. Just keep in mind that the times on the folders will more than likely be different, so you may want to use a regex to replace them and make them more consistent, since that's fairly benign (I used \sPM*\).Vim opens each file in a separate window and highlights the differences. It's still pretty manual, but it works well. ![]() Probably a similar technique like ls -alR > output I'm sure others have thoughts on doing this with *NIX. It actually hung when run on the server (that's where I had access to both sets of files) to a point that I had to force a quit. To solve this issue, I copied the files from the FAT32 to an NTFS drive.Īlso, DiffMerge is nice, but slow. NTFS against FAT32 doesn't work well, as one scans the folders in reverse alphabetical order, and the other doesn't. comparing a dev computer with productionĪ note on some lessons learned: dir /s /o:N > output.txt works well in conjunction with a text comparison tool (I used WinMerge), but the filesystem does appear to matter. Are there any good tools for comparing two folder structures (files included) between two environments?
