GIT-MERGETOOL(1)						    Git Manual							  GIT-MERGETOOL(1)

NAME

       git-mergetool - Run merge conflict resolution tools to resolve merge conflicts

SYNOPSIS

       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.

       If one or more <file> parameters are given, the merge tool program will be run to resolve differences on each file (skipping those without
       conflicts). Specifying a directory will include all unresolved files in that path. If no <file> names are specified, git mergetool will run
       the merge tool program on every file with merge conflicts.

OPTIONS

       -t <tool>, --tool=<tool>
	   Use the merge resolution program specified by <tool>. Valid merge tools are: araxis, bc3, diffuse, ecmerge, emerge, gvimdiff, kdiff3,
	   meld, opendiff, p4merge, tkdiff, tortoisemerge, vimdiff and xxdiff.

	   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 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 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 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 -t or --tool option or the merge.tool configuration variable) the
	   configured command line will be invoked with $BASE set to the name of a temporary file containing the common base for the merge, if
	   available; $LOCAL set to the name of a temporary file containing the contents of the file on the current branch; $REMOTE set to the
	   name of a temporary file containing the contents of the file to be merged, and $MERGED set to the name of the file to which the merge
	   tool should write the result of the merge resolution.

	   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. Otherwise, git mergetool will prompt the user to indicate the success of the
	   resolution after the custom tool has exited.

       -y, --no-prompt
	   Don't prompt before each invocation of the merge resolution program.

       --prompt
	   Prompt before each invocation of the merge resolution program. This is the default behaviour; the option is provided to override any
	   configuration settings.

TEMPORARY FILES

       git mergetool creates *.orig backup files while resolving merges. These are safe to remove once a file has been merged and its git
       mergetool session has completed.

       Setting the mergetool.keepBackup configuration variable to false causes git mergetool to automatically remove the backup as files are
       successfully merged.
