At its most basic level, +'git difftool' does what 'git mergetool' does but its use is for non-merge +situations such as when preparing commits or comparing changes against +the index. + +'git difftool' is a frontend to 'git diff' and accepts the same +arguments and options. + +See linkgit:git-diff[7] for the full list of supported options. + +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, and opendiff ++ +If a merge resolution program is not specified, 'git difftool' +will use the configuration variable `merge.tool`. If the +configuration variable `merge.tool` is not set, 'git difftool' +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 difftool' assumes the +tool is available in PATH. ++ +Instead of running one of the known merge tool programs, +'git difftool' can be customized to run an alternative program +by specifying the command line to invoke in a configuration +variable `mergetool.<tool>.cmd`. ++ +When 'git difftool' 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 the following +variables available: `$LOCAL` is set to the name of the temporary +file containing the contents of the diff pre-image and `$REMOTE` +is set to the name of the temporary file containing the contents +of the diff post-image. `$BASE` is provided for compatibility +with custom merge tool commands and has the same value as `$LOCAL`. + +--no-prompt:: + Do not prompt before launching a merge tool. + +CONFIG VARIABLES +---------------- +merge.tool:: + The default merge tool to use. ++ +See the `--tool=<tool>` option above for more details. + +merge.keepBackup:: + The original, unedited file content can be saved to a file with + a `.orig` extension. Defaults to `true` (i.e. keep the backup files). + +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. ++ +See the `--tool=<tool>` option above for more details. + + +SEE ALSO +-------- +linkgit:git-diff[7]:: + Show changes between commits, commit and working tree, etc + +linkgit:git-mergetool[1]:: + Run merge conflict resolution tools to resolve merge conflicts + +linkgit:git-config[7]:: + Get and set repository or global options + + +AUTHOR +------ +Written by David Aguilar <davvid@gmail.com>. + +Documentation +-------------- +Documentation by David Aguilar and the git-list <git@vger.kernel.org>. + +GIT +--- +Part of the linkgit:git[1] suite |
