--------------------
A revision parameter '<rev>' typically, but not necessarily, names a
-commit object. They use what is called an 'extended SHA1'
+commit object. It uses what is called an 'extended SHA1'
syntax. Here are various ways to spell object names. The
-ones listed near the end of this list are to name trees and
+ones listed near the end of this list name trees and
blobs contained in a commit.
'<sha1>', e.g. 'dae86e1950b1277e545cee180551750029cfe735', 'dae86e'::
The full SHA1 object name (40-byte hexadecimal string), or
- a substring of such that is unique within the repository.
+ a leading substring that is unique within the repository.
E.g. dae86e1950b1277e545cee180551750029cfe735 and dae86e both
- name the same commit object if there are no other object in
+ name the same commit object if there is no other object in
your repository whose object name starts with dae86e.
'<describeOutput>', e.g. 'v1.7.4.2-679-g3bee7fb'::
- An output from `git describe`; i.e. a closest tag, optionally
+ Output from `git describe`; i.e. a closest tag, optionally
followed by a dash and a number of commits, followed by a dash, a
'g', and an abbreviated object name.
When ambiguous, a '<name>' is disambiguated by taking the
first match in the following rules:
- . if '$GIT_DIR/<name>' exists, that is what you mean (this is usually
+ . If '$GIT_DIR/<name>' exists, that is what you mean (this is usually
useful only for 'HEAD', 'FETCH_HEAD', 'ORIG_HEAD', 'MERGE_HEAD'
and 'CHERRY_PICK_HEAD');
- . otherwise, 'refs/<name>' if exists;
+ . otherwise, 'refs/<name>' if it exists;
- . otherwise, 'refs/tags/<refname>' if exists;
+ . otherwise, 'refs/tags/<refname>' if it exists;
- . otherwise, 'refs/heads/<name>' if exists;
+ . otherwise, 'refs/heads/<name>' if it exists;
- . otherwise, 'refs/remotes/<name>' if exists;
+ . otherwise, 'refs/remotes/<name>' if it exists;
- . otherwise, 'refs/remotes/<name>/HEAD' if exists.
+ . otherwise, 'refs/remotes/<name>/HEAD' if it exists.

-'HEAD' names the commit your changes in the working tree is based on.
-'FETCH_HEAD' records the branch you fetched from a remote repository
+'HEAD' names the commit on which you based the changes in the working tree.
+'FETCH_HEAD' records the branch which you fetched from a remote repository
with your last `git fetch` invocation.
-'ORIG_HEAD' is created by commands that moves your 'HEAD' in a drastic
+'ORIG_HEAD' is created by commands that move your 'HEAD' in a drastic
way, to record the position of the 'HEAD' before their operation, so that

+you can easily change the tip of the branch back to the state before you ran

+'MERGE_HEAD' records the commit(s) which you are merging into your branch
when you run `git merge`.
-'CHERRY_PICK_HEAD' records the commit you are cherry-picking
+'CHERRY_PICK_HEAD' records the commit which you are cherry-picking
when you run `git cherry-pick`.

Note that any of the 'refs/*' cases above may come either from
A ref followed by the suffix '@' with a date specification
enclosed in a brace
pair (e.g. '\{yesterday\}', '\{1 month 2 weeks 3 days 1 hour 1
- second ago\}' or '\{1979-02-26 18:30:00\}') to specify the value
+ second ago\}' or '\{1979-02-26 18:30:00\}') specifies the value
of the ref at a prior point in time. This suffix may only be
used immediately following a ref name and the ref must have an
existing log ('$GIT_DIR/logs/<ref>'). Note that this looks up the state
'<refname>@\{<n>\}', e.g. 'master@\{1\}'::
A ref followed by the suffix '@' with an ordinal specification
- enclosed in a brace pair (e.g. '\{1\}', '\{15\}') to specify
+ enclosed in a brace pair (e.g. '\{1\}', '\{15\}') specifies
the n-th prior value of that ref. For example 'master@\{1\}'
is the immediate prior value of 'master' while 'master@\{5\}'
is the 5th prior value of 'master'. This suffix may only be used
'@\{<n>\}', e.g. '@\{1\}'::
You can use the '@' construct with an empty ref part to get at a
- reflog of the current branch. For example, if you are on the
- branch 'blabla', then '@\{1\}' means the same as 'blabla@\{1\}'.

+ branch 'blabla' then '@\{1\}' means the same as 'blabla@\{1\}'.
'@\{-<n>\}', e.g. '@\{-1\}'::
- The special construct '@\{-<n>\}' means the <n>th branch checked out
+ The construct '@\{-<n>\}' means the <n>th branch checked out
before the current one.
'<refname>@\{upstream\}', e.g. 'master@\{upstream\}', '@\{u\}'::
The suffix '@\{upstream\}' to a ref (short form '<refname>@\{u\}') refers to
- the branch the ref is set to build on top of. Missing ref defaults
+ the branch the ref is set to build on top of. A missing ref defaults
to the current branch.
'<rev>{caret}', e.g. 'HEAD{caret}, v1.5.1{caret}0'::
'<rev>{tilde}<n>', e.g. 'master{tilde}3'::
A suffix '{tilde}<n>' to a revision parameter means the commit
object that is the <n>th generation grand-parent of the named
- commit object, following only the first parent. I.e. '<rev>{tilde}3' is
+ commit object, following only the first parents. I.e. '<rev>{tilde}3' is
equivalent to '<rev>{caret}{caret}{caret}' which is equivalent to
- '<rev>{caret}1{caret}1{caret}1'. See below for a illustration of

the usage of this form.
'<rev>{caret}\{<type>\}', e.g. 'v0.99.8{caret}\{commit\}'::

'<rev>{caret}\{\}', e.g. 'v0.99.8{caret}\{\}'::
A suffix '{caret}' followed by an empty brace pair
'<rev>{caret}\{/<text>\}', e.g. 'HEAD^{/fix nasty bug}'::

pair that contains a text led by a slash,

the '<rev>' before '{caret}'.
a commit whose commit message matches the specified regular expression.
This name returns the youngest matching commit which is
reachable from any ref. If the commit message starts with a
- '!', you have to repeat that; the special sequence ':/!',
- followed by something else than '!' is reserved for now.
+ '!' you have to repeat that; the special sequence ':/!',
+ followed by something else than '!', is reserved for now.
The regular expression can match any part of the commit message. To
match messages starting with a string, one can use e.g. ':/^foo'.
':path' (with an empty part before the colon)
is a special case of the syntax described next: content
recorded in the index at the given path.
- A path starting with './' or '../' is relative to current working directory.
- The given path will be converted to be relative to working tree's root directory.
+ A path starting with './' or '../' is relative to the current working directory.

This is most useful to address a blob or tree from a commit or tree that has

+ the same tree structure as the working tree.
':<n>:<path>', e.g. ':0:README', ':README'::
A colon, optionally followed by a stage number (0 to 3) and a
colon, followed by a path, names a blob object in the
- index at the given path. Missing stage number (and the colon

that follows it) names a stage 0 entry. During a merge, stage
1 is the common ancestor, stage 2 is the target branch's version
(typically the current branch), and stage 3 is the version from
- the branch being merged.
+ the branch which is being merged.
Here is an illustration, by Jon Loeliger. Both commit nodes B
and C are parents of commit node A. Parent commits are ordered
