For many users, the command line tool “diff” on Fedora is the go-to when wanting to compare the differences between two files. However, there are also a healthy selection of graphical tools available in Fedora for comparing the differences between two and even three files. Three of the graphical diff tools available in Fedora are Meld, Kompare and Diffuse.
Meld is the graphical diff tool that contains a multitude of features, including 2 and 3 file comparisons, syntax highlighting, direct file editing, support for comparing whole directories, and support for version control (including git).
You can install meld on fedora via the Software application, or using the command sudo yum install meld
Diffuse is another GTK based graphical diff tool option, and provides support for manual correction of line matching, direct editing of files, syntax highlighting and version control support. Check out the diffuse features page for the full list of features.
You can install Diffuse on Fedora via the Software application, or using the command sudo yum install diffuse
Kompare is a graphical diff tool from KDE, and features the ability to compare two text files, recursive directory comparisons, the ability to view patches, and to merge a patch into a directory.
