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 variablemerge.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 settingmergetool.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 themerge.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 totrue
. 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 themerge.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 configuredmerge.guitool
variable instead ofmerge.tool
. Ifmerge.guitool
is not set, we will fallback to the tool configured undermerge.tool
. - --no-gui
-
This overrides a previous
-g
or--gui
setting and reads the default merge tool will be read from the configuredmerge.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 canceldiff.orderFile
, use-O/dev/null
.
CONFIGURATION
- mergetool.<tool>.path
-
Override the path for the given tool. This is useful in case your tool is not in the PATH.
- mergetool.<tool>.cmd
-
Specify the command to invoke the specified merge tool. The specified command is evaluated in shell with the following variables available: BASE is the name of a temporary file containing the common base of the files to be merged, if available; LOCAL is the name of a temporary file containing the contents of the file on the current branch; REMOTE is the name of a temporary file containing the contents of the file from the branch being merged; MERGED contains the name of the file to which the merge tool should write the results of a successful merge.
- mergetool.<tool>.hideResolved
-
Allows the user to override the global
mergetool.hideResolved
value for a specific tool. Seemergetool.hideResolved
for the full description. - mergetool.<tool>.trustExitCode
-
For a custom merge command, specify whether the exit code of the merge command can be used to determine whether the merge was successful. If this is not set to true then the merge target file timestamp is checked and the merge assumed to have been successful if the file has been updated, otherwise the user is prompted to indicate the success of the merge.
- mergetool.meld.hasOutput
-
Older versions of
meld
do not support the--output
option. Git will attempt to detect whethermeld
supports--output
by inspecting the output ofmeld --help
. Configuringmergetool.meld.hasOutput
will make Git skip these checks and use the configured value instead. Settingmergetool.meld.hasOutput
totrue
tells Git to unconditionally use the--output
option, andfalse
avoids using--output
. - mergetool.meld.useAutoMerge
-
When the
--auto-merge
is given, meld will merge all non-conflicting parts automatically, highlight the conflicting parts and wait for user decision. Settingmergetool.meld.useAutoMerge
totrue
tells Git to unconditionally use the--auto-merge
option withmeld
. Setting this value toauto
makes git detect whether--auto-merge
is supported and will only use--auto-merge
when available. A value offalse
avoids using--auto-merge
altogether, and is the default value. - mergetool.hideResolved
-
During a merge Git will automatically resolve as many conflicts as possible and write the MERGED file containing conflict markers around any conflicts that it cannot resolve; LOCAL and REMOTE normally represent the versions of the file from before Git’s conflict resolution. This flag causes LOCAL and REMOTE to be overwriten so that only the unresolved conflicts are presented to the merge tool. Can be configured per-tool via the
mergetool.<tool>.hideResolved
configuration variable. Defaults tofalse
. - mergetool.keepBackup
-
After performing a merge, the original file with conflict markers can be saved as a file with a
.orig
extension. If this variable is set tofalse
then this file is not preserved. Defaults totrue
(i.e. keep the backup files). - mergetool.keepTemporaries
-
When invoking a custom merge tool, Git uses a set of temporary files to pass to the tool. If the tool returns an error and this variable is set to
true
, then these temporary files will be preserved, otherwise they will be removed after the tool has exited. Defaults tofalse
. - mergetool.writeToTemp
-
Git writes temporary BASE, LOCAL, and REMOTE versions of conflicting files in the worktree by default. Git will attempt to use a temporary directory for these files when set
true
. Defaults tofalse
. - mergetool.prompt
-
Prompt before each invocation of the merge resolution program.
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.
