git-difftool(1) |

=============== |

NAME |
|
---- |
|
git-difftool - compare changes using common merge tools |
|
|
|
SYNOPSIS |
|
-------- |
|
'git difftool' [--tool=<tool>] [--no-prompt] ['git diff' options] |
|
|
|
DESCRIPTION |
|
----------- |
|
'git-difftool' is a git command that allows you to compare and edit files |
|
between revisions using common merge tools. 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[1] 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, kompare, 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 diff 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. |
