- Visual diff and merge tool for the GNOME Desktop
[options] FILE1 FILE2 [FILE3]
[options] DIR1 DIR2 [DIR3]
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 DIR1
