meld [options] FILE1 FILE2 [FILE3]
meld [options] DIR1 DIR2 [DIR3]

DESCRIPTION

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.

OPTIONS

--auto-compare, -a

Automatically compare all differing files on startup.

--auto-merge

Automatically merge files

--comparison-file=<file>

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

--version

Print application version and exit.

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
