GIT-WHATCHANGED(1)                                    Git Manual                                   GIT-WHATCHANGED(1)



NAME
       git-whatchanged - Show logs with difference each commit introduces

SYNOPSIS
       git whatchanged <option>...


DESCRIPTION
       Shows commit logs and diff output each commit introduces. The command internally invokes git rev-list piped to
       git diff-tree, and takes command line options for both of these commands.

       This manual page describes only the most frequently used options.

OPTIONS
       -p
           Show textual diffs, instead of the Git internal diff output format that is useful only to tell the changed
           paths and their nature of changes.

       -<n>
           Limit output to <n> commits.

       <since>..<until>
           Limit output to between the two named commits (bottom exclusive, top inclusive).

       -r
           Show Git internal diff output, but for the whole tree, not just the top level.

       -m
           By default, differences for merge commits are not shown. With this flag, show differences to that commit
           from all of its parents.

           However, it is not very useful in general, although it is useful on a file-by-file basis.

       --pretty[=<format>], --format=<format>
           Pretty-print the contents of the commit logs in a given format, where <format> can be one of oneline,
           short, medium, full, fuller, email, raw and format:<string>. See the "PRETTY FORMATS" section for some
           additional details for each format. When omitted, the format defaults to medium.

           Note: you can specify the default pretty format in the repository configuration (see git-config(1)).

       --abbrev-commit
           Instead of showing the full 40-byte hexadecimal commit object name, show only a partial prefix. Non
           default number of digits can be specified with "--abbrev=<n>" (which also modifies diff output, if it is
           displayed).

           This should make "--pretty=oneline" a whole lot more readable for people using 80-column terminals.

       --no-abbrev-commit
           Show the full 40-byte hexadecimal commit object name. This negates --abbrev-commit and those options which
           imply it such as "--oneline". It also overrides the log.abbrevCommit variable.

       --oneline
           This is a shorthand for "--pretty=oneline --abbrev-commit" used together.

       --encoding[=<encoding>]
           The commit objects record the encoding used for the log message in their encoding header; this option can
           to be in refs/notes/ if it is not qualified.

           Multiple --notes options can be combined to control which notes are being displayed. Examples:
           "--notes=foo" will show only notes from "refs/notes/foo"; "--notes=foo --notes" will show both notes from
           "refs/notes/foo" and from the default notes ref(s).

       --no-notes
           Do not show notes. This negates the above --notes option, by resetting the list of notes refs from which
           notes are shown. Options are parsed in the order given on the command line, so e.g. "--notes --notes=foo
           --no-notes --notes=bar" will only show notes from "refs/notes/bar".

       --show-notes[=<ref>], --[no-]standard-notes
           These options are deprecated. Use the above --notes/--no-notes options instead.

       --show-signature
           Check the validity of a signed commit object by passing the signature to gpg --verify and show the output.

PRETTY FORMATS
       If the commit is a merge, and if the pretty-format is not oneline, email or raw, an additional line is
       inserted before the Author: line. This line begins with "Merge: " and the sha1s of ancestral commits are
       printed, separated by spaces. Note that the listed commits may not necessarily be the list of the direct
       parent commits if you have limited your view of history: for example, if you are only interested in changes
       related to a certain directory or file.

       There are several built-in formats, and you can define additional formats by setting a pretty.<name> config
       option to either another format name, or a format: string, as described below (see git-config(1)). Here are
       the details of the built-in formats:

       ·   oneline

               <sha1> <title line>

           This is designed to be as compact as possible.

       ·   short

               commit <sha1>
               Author: <author>

               <title line>

       ·   medium

               commit <sha1>
               Author: <author>
               Date:   <author date>

               <title line>

               <full commit message>

       ·   full

               commit <sha1>
               Commit:     <committer>
               CommitDate: <committer date>

               <title line>

               <full commit message>

       ·   email

               From <sha1> <date>
               From: <author>
               Date: <author date>
               Subject: [PATCH] <title line>

               <full commit message>

       ·   raw

           The raw format shows the entire commit exactly as stored in the commit object. Notably, the SHA-1s are
           displayed in full, regardless of whether --abbrev or --no-abbrev are used, and parents information show
           the true parent commits, without taking grafts nor history simplification into account.

       ·   format:<string>

           The format:<string> format allows you to specify which information you want to show. It works a little bit
           like printf format, with the notable exception that you get a newline with %n instead of \n.

           E.g, format:"The author of %h was %an, %ar%nThe title was >>%s<<%n" would show something like this:

               The author of fe6e0ee was Junio C Hamano, 23 hours ago
               The title was >>t4119: test autocomputing -p<n> for traditional diff input.<<

           The placeholders are:

           ·   %H: commit hash

           ·   %h: abbreviated commit hash

           ·   %T: tree hash

           ·   %t: abbreviated tree hash

           ·   %P: parent hashes

           ·   %p: abbreviated parent hashes

           ·   %an: author name

           ·   %aN: author name (respecting .mailmap, see git-shortlog(1) or git-blame(1))

           ·   %ae: author email

           ·   %aE: author email (respecting .mailmap, see git-shortlog(1) or git-blame(1))

           ·   %cN: committer name (respecting .mailmap, see git-shortlog(1) or git-blame(1))

           ·   %ce: committer email

           ·   %cE: committer email (respecting .mailmap, see git-shortlog(1) or git-blame(1))

           ·   %cd: committer date

           ·   %cD: committer date, RFC2822 style

           ·   %cr: committer date, relative

           ·   %ct: committer date, UNIX timestamp

           ·   %ci: committer date, ISO 8601 format

           ·   %d: ref names, like the --decorate option of git-log(1)

           ·   %e: encoding

           ·   %s: subject

           ·   %f: sanitized subject line, suitable for a filename

           ·   %b: body

           ·   %B: raw body (unwrapped subject and body)

           ·   %N: commit notes

           ·   %GG: raw verification message from GPG for a signed commit

           ·   %G?: show "G" for a Good signature, "B" for a Bad signature, "U" for a good, untrusted signature and
               "N" for no signature

           ·   %GS: show the name of the signer for a signed commit

           ·   %GK: show the key used to sign a signed commit

           ·   %gD: reflog selector, e.g., refs/stash@{1}

           ·   %gd: shortened reflog selector, e.g., stash@{1}

           ·   %gn: reflog identity name

           ·   %gN: reflog identity name (respecting .mailmap, see git-shortlog(1) or git-blame(1))

           ·   %ge: reflog identity email

           ·   %gE: reflog identity email (respecting .mailmap, see git-shortlog(1) or git-blame(1))

           ·   %gs: reflog subject

           ·   %Cred: switch color to red

           ·   %m: left, right or boundary mark

           ·   %n: newline

           ·   %%: a raw %

           ·   %x00: print a byte from a hex code

           ·   %w([<w>[,<i1>[,<i2>]]]): switch line wrapping, like the -w option of git-shortlog(1).

           ·   %<(<N>[,trunc|ltrunc|mtrunc]): make the next placeholder take at least N columns, padding spaces on
               the right if necessary. Optionally truncate at the beginning (ltrunc), the middle (mtrunc) or the end
               (trunc) if the output is longer than N columns. Note that truncating only works correctly with N >= 2.

           ·   %<|(<N>): make the next placeholder take at least until Nth columns, padding spaces on the right if
               necessary

           ·   %>(<N>), %>|(<N>): similar to %<(<N>), %<|(<N>) respectively, but padding spaces on the left

           ·   %>>(<N>), %>>|(<N>): similar to %>(<N>), %>|(<N>) respectively, except that if the next placeholder
               takes more spaces than given and there are spaces on its left, use those spaces

           ·   %><(<N>), %><|(<N>): similar to % <(<N>), %<|(<N>) respectively, but padding both sides (i.e. the text
               is centered)

           Note
           Some placeholders may depend on other options given to the revision traversal engine. For example, the %g*
           reflog options will insert an empty string unless we are traversing reflog entries (e.g., by git log -g).
           The %d placeholder will use the "short" decoration format if --decorate was not already provided on the
           command line.

       If you add a + (plus sign) after % of a placeholder, a line-feed is inserted immediately before the expansion
       if and only if the placeholder expands to a non-empty string.

       If you add a - (minus sign) after % of a placeholder, line-feeds that immediately precede the expansion are
       deleted if and only if the placeholder expands to an empty string.

       If you add a ` ` (space) after % of a placeholder, a space is inserted immediately before the expansion if and
       only if the placeholder expands to a non-empty string.

       ·   tformat:

           The tformat: format works exactly like format:, except that it provides "terminator" semantics instead of
           "separator" semantics. In other words, each commit has the message terminator character (usually a
           newline) appended, rather than a separator placed between entries. This means that the final entry of a
           single-line format will be properly terminated with a new line, just as the "oneline" format does. For
           example:

               $ git log -2 --pretty=format:%h 4da45bef \
                 | perl -pe '$_ .= " -- NO NEWLINE\n" unless /\n/'
               4da45be
               7134973 -- NO NEWLINE


EXAMPLES
       git whatchanged -p v2.6.12.. include/scsi drivers/scsi
           Show as patches the commits since version v2.6.12 that changed any file in the include/scsi or
           drivers/scsi subdirectories

       git whatchanged --since="2 weeks ago" -- gitk
           Show the changes during the last two weeks to the file gitk. The "--" is necessary to avoid confusion with
           the branch named gitk
