Meld is a graphical diff viewer and merge application for the GNOME desktop. It supports 2 and 3-file diffs, recursive directory diffs, diffing of directories under version control (Bazaar, CVS, Darcs, Fossil, Git, Mercurial, Monotone), as well as the ability to manually and automatically merge file differences.
- --auto-compare, -a
Automatically compare all differing files on startup.
Automatically merge files
Load a saved comparison from a Meld comparison file
- --diff FILE1|DIR1 FILE2|DIR2 [FILE3|DIR3]
Create a diff tab for the given files or directories. Note that "meld --diff FILE1 FILE2" is functionally equivalent to "meld FILE1 FILE2". However, the --diff argument can be given multiple times for one invocation of meld which allows the user to automatically initiate multiple diffs when meld starts. See examples below.
- --help, -h
Print application help and usage.
- --label=<label>, -L <label>
Set application window title to <label>.
- --newtab, -n
Open the comparison as a new tab in an already-running instance.
- --output, -o
Sets the save path for the middle buffer in a three-pane merge view. This is useful for loading the middle buffer from one file and saving it to another, for example in use as a version control merge helper.
- --unified, -u
Ignored for compatibility
Print application version and exit.
Run meld without initiating a diff.
- meld FILE1
Initiate a diff between FILE1 and the version-controlled copy of FILE1.
- meld DIR1
Initiate a recursive diff between DIR1 and the version-controlled copy of DIR1.
- meld FILE1 FILE2
Initiate a diff between FILE1 and FILE2.
- meld FILE1 FILE2 FILE3
Initiate a 3-way diff between FILE1, FILE2, and FILE3.
- meld DIR1 DIR2
Initiate a recursive diff between directory DIR1 and DIR2.
- meld DIR1 DIR2 DIR3
Initiate a recursive 3-way diff between directory DIR1, DIR2, and DIR3.
- meld --diff FILE1 FILE2 --diff FILE3 FILE4
Initiate a diff between FILE1 and FILE2, and a separate diff between FILE3 and FILE4.
