The "--amend" option comes in handy, for example, when you mistyped the last commit's message or forgot to add a change. The following example will correct the very last commit by overwriting its message and adding another change:. You'll find the most important commands on the front and helpful best practice tips on the back. Over , developers have downloaded it to make Git a little bit easier. Just like with Tower, our mission with this platform is to help people become better professionals.
That's why we provide our guides, videos, and cheat sheets about version control with Git and lots of other topics for free. First Aid Kit Learn how to undo and recover from mistakes with our handy videos series and cheat sheet. Webinar Join a live Webinar and learn from a Git professional.
Video Course 24 episodes explain Git and version control step-by-step, one topic per video. The regex can also be set via a diff driver or configuration option, see gitattributes[5] or git-config[1].
Giving it explicitly overrides any diff driver or configuration setting. Diff drivers override configuration settings. Warn if changes introduce conflict markers or whitespace errors. What are considered whitespace errors is controlled by core.
By default, trailing whitespaces including lines that consist solely of whitespaces and a space character that is immediately followed by a tab character inside the initial indent of the line are considered whitespace errors. Exits with non-zero status if problems are found.
Not compatible with --exit-code. Highlight whitespace errors in the context , old or new lines of the diff. Multiple values are separated by comma, none resets previous values, default reset the list to new and all is a shorthand for old,new,context. When this option is not given, and the configuration variable diff. The whitespace errors are colored with color. Instead of the first handful of characters, show the full pre- and post-image blob object names on the "index" line when generating patch format output.
In addition to --full-index , output a binary diff that can be applied with git-apply. In diff-patch output format, --full-index takes higher precedence, i.
If generating diffs, detect and report renames for each commit. For following files across renames while traversing history, see --follow. If n is specified, it is a threshold on the similarity index i.
Detect copies as well as renames. See also --find-copies-harder. For performance reasons, by default, -C option finds copies only if the original file of the copy was modified in the same changeset. This flag makes the command inspect unmodified files as candidates for the source of copy.
This is a very expensive operation for large projects, so use it with caution. Giving more than one -C option has the same effect. Omit the preimage for deletes, i. The resulting patch is not meant to be applied with patch or git apply ; this is solely for people who want to just concentrate on reviewing the text after the change.
In addition, the output obviously lacks enough information to apply such a patch in reverse, even manually, hence the name of the option. For renames, only remaining unpaired sources are relevant; for copies, all original sources are relevant.
Note that a value of 0 is treated as unlimited. Any combination of the filter characters including none can be used. Also, these upper-case letters can be downcased to exclude. Note that not all diffs can feature all types. For instance, diffs from the index to the working tree can never have Added entries because the set of paths included in the diff is limited by what is in the index. Similarly, copied and renamed entries cannot appear if detection for those types is disabled.
Look for differences that change the number of occurrences of the specified string i. Unless --text is supplied patches of binary files without a textconv filter will be ignored. See the pickaxe entry in gitdiffcore[7] for more information. Look for differences that change the number of occurrences of the specified object. The object can be a blob or a submodule commit.
It implies the -t option in git-log to also find trees. Control the order in which files appear in the output. This overrides the diff. To cancel diff. All files with pathnames that match the first pattern are output first, all files with pathnames that match the second pattern but not the first are output next, and so on. All files with pathnames that do not match any pattern are output last, as if there was an implicit match-all pattern at the end of the file.
If multiple pathnames have the same rank they match the same pattern but no earlier patterns , their output order relative to each other is the normal order. Lines starting with a hash " " are ignored, so they can be used for comments. These were invented primarily for use of the git difftool command, and may not be very useful otherwise. When run from a subdirectory of the project, it can be told to exclude changes outside the directory and show pathnames relative to it with this option.
When you are not in a subdirectory e. This option may be specified more than once. Show the context between diff hunks, up to the specified number of lines, thereby fusing hunks that are close to each other. Show whole function as context lines for each change. The function names are determined in the same way as git diff works out patch hunk headers see Defining a custom hunk-header in gitattributes[5].
Allow an external diff helper to be executed. If you set an external diff driver with gitattributes[5] , you need to use this option with git-log[1] and friends. Allow or disallow external text conversion filters to be run when comparing binary files. See gitattributes[5] for details. Because textconv filters are typically a one-way conversion, the resulting diff is suitable for human consumption, but cannot be applied.
For this reason, textconv filters are enabled by default only for git-diff[1] and git-log[1] , but not for git-format-patch[1] or diff plumbing commands. Ignore changes to submodules in the diff generation. Using "none" will consider the submodule modified when it either contains untracked or modified files or its HEAD differs from the commit recorded in the superproject and can be used to override any settings of the ignore option in git-config[1] or gitmodules[5].
When "untracked" is used submodules are not considered dirty when they only contain untracked content but they are still scanned for modified content. Using "dirty" ignores all changes to the work tree of submodules, only changes to the commits stored in the superproject are shown this was the behavior until 1. Using "all" hides all changes to submodules. By default entries added by "git add -N" appear as an existing empty file in "git diff" and a new file in "git diff --cached".
