NAME

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

SYNOPSIS

       git mergetool [--tool=<tool>] [-y | --[no-]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 values include emerge, gvimdiff, kdiff3,
           meld, vimdiff, and tortoisemerge. Run git mergetool --tool-help for the list of valid <tool>
           settings.

           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.

       --tool-help
           Print a list of merge tools that may be used with --tool.

       -y, --no-prompt
           Don’t prompt before each invocation of the merge resolution program. This is the default if the merge
           resolution program is explicitly specified with the --tool option or with the merge.tool
           configuration variable.

       --prompt
           Prompt before each invocation of the merge resolution program to give the user a chance to skip the
           path.

       -g, --gui
           When git-mergetool is invoked with the -g or --gui option the default merge tool will be read from
           the configured merge.guitool variable instead of merge.tool. If merge.guitool is not set, we will
           fallback to the tool configured under merge.tool.

       --no-gui
           This overrides a previous -g or --gui setting and reads the default merge tool will be read from the
           configured merge.tool variable.

       -O<orderfile>
           Process files in the order specified in the <orderfile>, which has one shell glob pattern per line.
           This overrides the diff.orderFile configuration variable (see git-config(1)). To cancel
           diff.orderFile, use -O/dev/null.

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.
