SYNOPSIS
--------
-'git mergetool' [--tool=<tool>] [<file>]...
+'git mergetool' [--tool=<tool>] [-y|--no-prompt|--prompt] [<file>]...
DESCRIPTION
-----------
Use `git mergetool` to run one of several merge utilities to resolve
-merge conflicts. It is typically run after 'git-merge'.
+merge conflicts. It is typically run after 'git merge'.
If one or more <file> parameters are given, the merge tool program will
be run to resolve differences on each file. If no <file> names are
-specified, 'git-mergetool' will run the merge tool program on every file
+specified, 'git mergetool' will run the merge tool program on every file
with merge conflicts.
OPTIONS
-------
--t or --tool=<tool>::
+-t <tool>::
+--tool=<tool>::
Use the merge resolution program specified by <tool>.
Valid merge tools are:
- kdiff3, tkdiff, meld, xxdiff, emerge, vimdiff, gvimdiff, ecmerge, and opendiff
+ kdiff3, tkdiff, meld, xxdiff, emerge, vimdiff, gvimdiff, ecmerge,
+ diffuse, tortoisemerge, opendiff, p4merge and araxis.
+
-If a merge resolution program is not specified, 'git-mergetool'
+If a merge resolution program is not specified, 'git mergetool'
will use the configuration variable `merge.tool`. If the
-configuration variable `merge.tool` is not set, 'git-mergetool'
+configuration variable `merge.tool` is not set, 'git mergetool'
will pick a suitable default.
+
You can explicitly provide a full path to the tool by setting the
configuration variable `mergetool.<tool>.path`. For example, you
can configure the absolute path to kdiff3 by setting
-`mergetool.kdiff3.path`. Otherwise, 'git-mergetool' assumes the
+`mergetool.kdiff3.path`. Otherwise, 'git mergetool' assumes the
tool is available in PATH.
+
Instead of running one of the known merge tool programs,
-'git-mergetool' can be customized to run an alternative program
+'git mergetool' can be customized to run an alternative program
by specifying the command line to invoke in a configuration
variable `mergetool.<tool>.cmd`.

-When 'git-mergetool' is invoked with this tool (either through the
+When 'git mergetool' is invoked with this tool (either through the
`-t` or `--tool` option or the `merge.tool` configuration
variable) the configured command line will be invoked with `$BASE`

If the custom merge tool correctly indicates the success of a
merge resolution with its exit code, then the configuration
variable `mergetool.<tool>.trustExitCode` can be set to `true`.
