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. 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: kdiff3, tkdiff, meld, xxdiff, emerge, vimdiff, gvimdiff,
ecmerge, diffuse, tortoisemerge, opendiff, p4merge and araxis.
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.
